I'm getting almost the same error as in Issue #22 - Issue with lk.cpp and openCV 2.3.1

I'm running Windows 7 x64, MatLab r2010a, CV 2.3.1 and VS 2010.
It all compiles and links fine, finally, but when I try to run run_TLD it gives me :

lk(2,imgI,imgJ,ptsI,ptsJ,Level)
??? One or more output arguments not assigned during call to "lk".

Error in ==> tldTracking at 30

Error in ==> tldExample at 41
tld = tldProcessFrame(tld,i); % process frame i

Error in ==> run_TLD at 42

I tried the change mentioned in Issue #22. Change the 10th param in xFJ from 0 to status, but that didn't change anything.

Hello,

I get the following error when I run the patched compile.m on Mac OS X

 Mac
 /Applications/MATLAB_R2010b.app/bin/mex: line 305: gcc-4.0: command not found
 /Applications/MATLAB_R2010b.app/bin/mex: line 1041: g++-4.0: command not found

     mex: compile of ' "lk.cpp"' failed.

 ??? Error using ==> mex at 208

I have gcc-4.2.1 on my computer. How can I tell Matlab or mex to use this compiler?

Hi there. I'm trying to run the TLD algorithm on Ubuntu 16.04 (64-bit) and MatLAB R2016b

I have not installed openCV, but rather the libraries as stated in the installation guide by

sudo apt-get install libcv-dev

When running compile.m from within MatLAB I get the error (s)

I have implemented the changes to the files as in Schloegl's pull request and thought this would sort out the error (s) I thought there were between linking MatLAB and OpenCV's libraries

As per this thread https://groups.google.com/forum/#!topic/opentld/zrQS4SPJq9o (and others I think), I think it would be good if someone wrote some logic for automatic camera detection. Shouldn't be too difficult I'd think. Unfortunately, I can't do it, I don't have a computer with both Matlab and a webcam. :-(
Relevant code: https://github.com/zk00006/OpenTLD/blob/master/initcamera.m#L26

I tried to compile and run OpenTLD on 64bit Ubuntu. Compilation was ok with OpenCV 2.3.1 (older versions have some problems with headers).

Then I try to run, I can see the first frame and then the following error:

Anyone got an idea what could be wrong?

Hi, all

In training the forest classifier, I don't quite the following steps like measure_forest:
if (Y[I] == 1) {
if (measure_forest(x) <= thrP)
update(x,1,1);
} else {
if (measure_forest(x) >= thrN)
update(x,0,1);
}
Why the training set is controlled by thrP or thrN? In my view, as far as we get the positive samples and negative samples in prior, just update the forest with those samples. What is the purpose of measure_forest? Any one knows? Thanks in advance.

Matlab isn't very nice for integration with other software -- it would be great to have a version of TLD written in C or C++ :)

I'm interested in implementing it in C/C++, if there are no current plans to do so in the near future.

Hy All!

My windows decided to give me some BSOD, so I had to get a new win os.
So the point is...
I have win7 x 64, Visual Studio 2010, and if I use Matlab 2010a with the patch, shall I use OpenCV2.2 for Win32?
(Anyway making OpenCv compatible for win7x64 is kinda messy for me. )

Thanks for the answer.

Please add information about which software package versions were used/are minimum requirement for this code. This would save much effort with hunting down mysterious problems.
For example, for using ~ as a placeholder for unused functions, MATLAB >=R2009b is necessary.

Thanks,
christoph

I want to get the same shape for the input and output frame by using the TLD_demo, where should I do modification?

I am getting this error when i try to execute run_TLD.m (compilation went fine)

I was tracking an object in the movie but the tracking is too slow, approximately 6-9 fps. I was wondering if anyone know how to track accurately in real-time i.e. approximately 20-25 fps.
Any pointers would be much appreciated. Thanks

I would like to know what are the toolboxes required for the tld to work

Thank you
Edwin

I'm running
Windows 7 (x64),
MATLAB R2012b (x64),
OpenCV 2.4.3 (x64),
and VS 2010.

I managed to compile OpenTLD successfully, but I got the following error why I tried run_TLD. Obviously this is a problem in the opencv matrix.cpp file. I usually run opencv on visual studio and there is no problem, so this shouldn't be my opencv installation problem.

First off, I'm only posting here because I don't have access to the google group (I've been waiting about a month now, who can give me access?)

I'm using Matlab 2011a, Ubuntu 11.04, and OpenCV 2.3.1. I got the compile.m file to run with no errors successfully, however I get error when I run run_TLD.m

Here is my output:

??? Invalid MEX-file '/home/ryan/OpenTLD/mex/lk.mexa64': /usr/lib/libcairo.so.2: undefined

Error in ==> tldExample at 34
tld = tldInit(opt,[]); % train initial detector and initialize the 'tld' structure

Error in ==> run_TLD at 42

There were some other posts very similar to this, but they seemed to address the GCC compiler version error, which I have already fixed on my system (currently using GCC 4.3.5, compile.m runs correctly)

Any help is greatly appreciated. And access to the group would be great so I can look for issues I encounter in the future.

Thank you,

Ryan

After following the installation instructions and running the compile.m successfully. I tried to run run_TLD.m and this error happens :

Invalid MEX-file 'C:\Users\myname\Documents\GitHub\OpenTLD\mex\lk.mexw64': The specified module could not be found.

Please advise on this as I have search google and everything for help. The best I got was that that this will happen if I dont have the neccessary dlls that the mex file requires. Please help!!

Thanks

I've been trying to test using larger resolutions.

I've gotten images around 2000px by 900px to work but anything above that cause the program to crash.

I modified the example code to be able to load videofiles directly in Matlab.
Hope anyone else finds this helpful, so I include the diff here: https://gist.github.com/922938

I am trying to install Octave 3.4.0 on my laptop, and when I try to do the step "make', the following error always occurs. Anyone can help? Thank you.

I was wondering how difficult it would be to track multiple objects, within the same instance..

Does anybody have any hints on the best way to do this ?

Hi all,

I think there is a possible bug in the fern.cpp code. Under mex/fern.cpp, line 430, I believe the code should be:

double bboxvar = bbox_var_offset(IIMG,IIMG2,BBOX+(idx[j]-1)*BBOX_STEP);

The code in the current version is:

double bboxvar = bbox_var_offset(IIMG,IIMG2,BBOX+j*BBOX_STEP);

This means that no matter which bounding box locations that have been found with the least amount of overlap, we will only be using the first numIdx indexed locations in the BBOX array, and not the ones with the least amount of overlap.

Not sure where to post this, so I figured this was the best spot to do so.

Thanks,

• Ray.

Running the demo from the bilderbuchi fork on Ubuntu with Octave 3.4 (compiled from source) works, however, the tracker is able to track the motorcycle in the first two frames/images, after that it produces NaN,NaN,NaN,NaN,NaN.

First i installed opencv from here: http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.2/OpenCV-2.2.0-win32-vs2010.exe/download and selected 'add path to variables.'
Second i wrote 'mex -setup' and select Visual studio 2010.

Finally i open the source folder in Matlab, run the file compile.m and got:

Hi, All
I'v already installed the 'TLD1.0_demo', etc. It run very well from my Windows 7 - 64 bit.

Now, I want to edit the code from 'zk00006-OpenTLD-8a6934d' in MATLAB.
However, if I want to run from 'run_TLD.m' , it can't run.

        ??? Undefined function or method 'lk' for input arguments of type 'double'. 
        Error in ==> tldInit at 20

        Error in ==> run_TLD at 42 
        [bb,conf] = tldExample(opt); 

My Questions :

1. WHY ? Should I run all of the .m files which are inside of 'zk00006-OpenTLD-8a6934d' ?
2. Or should I install another software like OpenCV and VisualStudio to make it 'Run' ?
3. Should I make it into .exe files instead of directly edit & click run in MATLAB ?
4. Ow do you have any idea, which .m file should I edit if the TLD shows the x,y,s position like Zdenek Kalal video ?

Thanks all

Hey there!

I would like to use TLD for my PhD and I have two issues that maybe somebody could help me with.

First, I Need to record the position of the box at each frame and write it in my output data. Any idea?

Second, I would like to make TLD able to re-use what it has learned in a previous tracking. Any suggestion?

All the best!

hi, when run the code with Kalal's in matlab the step compile task has successfully finished,but happen a wrong in runing run_TLD see following:
??? Invalid MEX-file

i donnot kown why and how to solve it . in the mex folder there is a file lk.mexw32 which comes after taking compile task, so i donot the real reason of the problem!!!

I followed the download instructions, and after fixing the include directories, etc., and getting the "compile.m" function to work successfully, I then tried to run the tracker on a directory of images. Things seemed to work OK for a second, and the first image within my directory popped up with the interactive bounding box as seen in the tutorial. I tried to select the initial bounding box of a face and double clicked inside it and received this error in the Matlab console:

Can anybody help me?
I ran the Open TLD and it is working fine.
Now I just want to use my own video and track the object.
For that I need to re-size the yellow box and move the co-ordinates.
Could you tell me which .m file I should be updating to achieve this?

From what I have gathered, OpenTLD is a tracker and detector, it tracks what you tell it to and detects the object frame by frame. I feel that this can be applied to the broader scope of object recognition, where the software learns many object and can name the objects it sees in a frame. I'm aware of openTLD's one object tracking limitations, but there shouldn't be a limitation to find all the recognizable objects correct? It should be able to go through the database of saved objects and look for those objects in a frame.

Any thoughts on this? Can this be done easily? Better yet, has anyone made modifications for this already?

thanks

At present when I load a movie from a file , it tracks it in grayscale mode. Does anyone know how to track it in RGB or color mode.

Thanks

I know it has something to do with using wrong bit version(32/64) of one of the OpenCV or Matlab to build, but still can't resolve the issue.

I got errors with MEX not being able to find the appropriate SDK (it couldn't find clang).

I ran some video containing human moving and want to tracking that human. I run example video "motor bike" with a good result. 👍
But when I run on my video, it produces lousy results. Yellow bounding box sometimes does not move. Is there anyone supported this project, pls have a discussion.

Hi,
I am trying to use TLD for the first time. I changed the path in compile.m file
based on the instruction on page https://github.com/zk00006/OpenTLD/wiki/Installation
In Original TLD opencv2.2 was used I modified my libpath to include files 'libopencv*so.3.3'
The compile file ran without any errors.

However, I try to run run_TLD.m I get the following error.
Invalid MEX-file '/home/ITS/abshinde/Downloads/OpenTLD-master/mex/lk.mexa64': libopencv_calib3d.so.3.3: cannot open shared object file: No such file or
directory.
Error in ==> tldInit at 20
lk(0);
Error in ==> tldExample at 34
tld = tldInit(opt,[]); % train initial detector and initialize the 'tld' structure
Error in ==> run_TLD at 42
[bb,conf] = tldExample(opt);

I tried searching on forums but could not get relevant info. Can you point me in right direction

I got this error when i tried to compile TLD

Hi,

When I try to run this program I'm getting the following error, "The file requires the following codec(s) to be installed on your system: video/x-cinepak". I'm using a AVI file as video input. Has anyone faced this issue before? Could you please suggest a solution?

Thanks and regards,

Hi,

I am using Matlab R2011a and openCV 2.3.1 on a MacBook Pro (os x 10.6.8).

I successfully compiled the mex files as detailed here: https://github.com/zk00006/OpenTLD/wiki/Installation.

However, at runtime, I received the following error:

??? Unexpected Standard exception from MEX file.
What() is:/Users/liam/projects/OpenCV-2.3.1/modules/core/src/matrix.cpp:1305:
error: (-27) create() called for the missing output array in function create

Error in ==> tldTracking at 30

and NCC for each point

Error in ==> tldProcessFrame at 25

Error in ==> tldExample at 41
tld = tldProcessFrame(tld,i); % process frame i

Error in ==> run_TLD at 43
[bb,conf] = tldExample(opt);

I tracked the problem down to line 186 of lk.cpp, and changed the line from:

        cvCalcOpticalFlowPyrLK( IMG[J], IMG[I], PYR[J], PYR[I], points[1], points[2], nPts, cvSize(win_size,win_size), Level, 0     , 0, cvTermCriteria(CV_TERMCRIT_ITER|CV_TERMCRIT_EPS,20,0.03), CV_LKFLOW_INITIAL_GUESSES | CV_LKFLOW_PYR_A_READY | CV_LKFLOW_PYR_B_READY );

to:

        cvCalcOpticalFlowPyrLK( IMG[J], IMG[I], PYR[J], PYR[I], points[1], points[2], nPts, cvSize(win_size,win_size), Level, status     , 0, cvTermCriteria(CV_TERMCRIT_ITER|CV_TERMCRIT_EPS,20,0.03), CV_LKFLOW_INITIAL_GUESSES | CV_LKFLOW_PYR_A_READY | CV_LKFLOW_PYR_B_READY );

i.e. changed the 10th argument from '0' to 'status', and this solved the problem.

Hope this helps.

I have found a possible bug resetting all the positive examples of the model. I guess it doesn't happen often, but have a look at this:

function [conf1,conf2,isin] = tldNN(x,tld)

isin = nan(3,size(x,2));

if isempty(tld.nex) % IF negative examples in the model are not defined THEN everything is positive
conf1 = ones(1,size(x,2));
conf2 = ones(1,size(x,2));
return;
end

then in tldTrainNN

   [conf1,~,isin] = tldNN(x(:,i),tld); % measure Relative similarity

   % Positive
   if y(i) == 1 && conf1 <= tld.model.thr_nn % 0.65
       if isnan(isin(2))
           tld.pex = x(:,i);
           continue;
       end

if there are no negative examples in the model (tld.nex), the list of positive ones (many possible) (tld.pex) will be reset to just one example!

Is it a desired behaviour?

Hy

The key event doesn't work for me properly. If I callback is on, it shuts down on any key event. But if I comment it out, it doesn't react at all, but it think function handleKey(~, evnt) should work (tdldemo.m). How can I make this work like in the demo?

And one more thing, I'd like to follow the detection with the cursor, how can I get out the cordinates? I thought maybe I could use the center of the bbox with an other extra cpp (winapi SetCursorPos), but it doesn't work.
I mean if I use even const in the SetC..Pos call, it puts the cursor on the left-upper corner (position zero-zero). Do you have any Idea about this?

My idea: In the tdldisplay.m I call bb_cent for the cp.

plot(cp(1,:),cp(2,:),'.','color','red');
bb_cent(cp);

bb_cent looks like this:

include <windows.h>

include "mex.h"

void bb_cent(double *bb1) {

int _x = bb1[0];
int _y = bb1[1];
SetCursorPos(_x, _y);

}

void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{

switch (nrhs) {

    case 0: {
        mexPrintf("Not enough argument");
        return;
            }

    case 1: {
        // Input
        double *bb1 = mxGetPr(prhs[0]);
        //bb_cent(bb1);
        SetCursorPos(900,450);
        return;
            }
}

}
But It doesn't put the cursor to the right point just only to the zero-zero. What causes this error? :S

I finally got opencv compiled and working with mountain lion. I can't get openTLD to compile in Matlab. I keep getting a flann error. and while I doubt this is the fault of openTLD, is there a workaround it?
