KAORI-INS - A Framework for Instance Search

1. IDE Setup

• Download Eclipse PDT: http://www.zend.com/en/company/community/pdt/downloads (Zend Eclipse PDT PDT 3.2.0 w/Eclipse Indigo (ZIP) 127.69 MB)
• Install on D:\zend-eclipse-php
• Install EGit: Eclipse/Help/Install New Software --> Paste link: http://download.eclipse.org/egit/updates (ref: http://www.eclipse.org/egit/download/)

2. New repository

• Create new repository kaori-ins: https://github.com/ledduy/kaori-ins.git

3. Clone

• to local D:\ for coding

• Ref: http://wiki.eclipse.org/EGit/User_Guide#Working_with_remote_Repositories
• Eclipse/Import

• to server V:\ (per900b/raid0/ledduy) cd /net/per900b/raid0/ledduy/github-projects git clone https://github.com/ledduy/kaori-ins.git

4. Datasets

• TV2011:

• 3 keyframes/sec
• Keyframe size; 352x288
• 20,982 clips --> 1,650,827 keyframes
• 25 topics (9023-9047)
• All videos were chopped into 20 to 10s clips using ffmpeg
• ~ 100 hours, BBC rushes
• Submission format:

• TV2012

• 3 keyframes/sec
• 33 keyframes/clip
• 74,958 clips --> 2,256,930
• 21 topics (9048-9068)
• Keyframe size: 640x480
• Flickr video
• Submission format:

• TV2013:

• 5 keyframes/sec
• Keyframe size: 768x576
• 471,526 shots --> 2,245,924 keyframes
• 30 topics (9069-9098)
• BBC EastEnders, approximately 244 video files (totally 300 GB, 464 h)
• Submission format:

5. Steps 5.1. Generate metadata (DONE Aug 12)

• Code: php -f ksc-Tool-GenerateMetaData.php 2011|2012|2013 test|query|queryext50
• Generate metadata for new corresponding pats, e.g. test2013-new
• For tv2011, tv2012 --> copy data to keyframe-5/tv2012/test2012-new/TRECVID2012_1/*.tar
• For tv2013 --> only 5KF/shot are copied and packed in .tar file.
• Running time on SGE (24 cores) for tv2013 is 16 hours, tv2012 & tv2011 is 4 hours.

5.2. Generate metadata for subtest --> only subtest2012-new

• Code: ksc-Tool-Tool-GenerateMetaDataForSubTest.php 2012
• Note: Copy *.tar files of selected shots to new dir (it is better to use softlink, but here cp is used).
• Shot sampling rate: $arSamplingRateList = array(2011 => 10, 2012 => 20, 2013 => 20);
• subtest2012-new:

• #keyframes: 146,966 (full: 2,256,930)
• #shots: ~98x50
• note: shots of groundtruth are also added.

5.2. Extract raw local features using colorsift

• Code: ksc-Feature-ExtractRawAffCovSIFTFeature-COLORSIFT*.*
• Max image size: 500x500 (specified in ksc-AppConfig.php)
• Keypoint detector: HarLap & Dense sampling (step size 6 pixel, 2 scales).
• Descriptor: SIFT and rgbSIFT.

***colordescriptor ver 3.0 - Processing time:

• harlap x rgbsift: 12 sec/KF
• harlap x sift: 7 sec/KF
• dense6 x rgbsift: 10 sec/KF
• dense6 x sift: 6 sec/KF
• note: colordescriptor auto resize large KF into max 500x500, and CPU is usually 2x

5.3. Running DPM model

• tv2012 ~ 4 sec/keyframe
• tv2013: 16 sec/keyframe for 2x scale factor on test keyframes, 6 sec/keyframe for normal KF.

*************************** RE-TEST THE FRAMEWORK **********************

6.1. Raw feature extraction

• Only dense6mul.sift is used for test2012-new

• Pat are defined in ksc-AppConfigForProject.php

• Total time: 6*2.25M/3600 = 3,750 hours (Aug23-23:30 --> [Aug25-->10:00 - Last jobs!])

• 56 cores until Aug25-03:00AM, 550 cores after that (INS deadline)

• test2011-new

• Aug26-->23:55 ==> Aug27-->9:55 - 1,000jobs*90mins/job = 1,500 hours (max 280 cores --> 150 cores because colordescriptor requires 1.5-2.0 CPUs *** Clustering

• Aug27-->10:10 ==> Aug27-->12:00

6.2. Quantization

• 1K codebook of subtest2012-new

• Total time: 6.5*2.25/3600 = 4,100 hours --> 20 hours (max 200 cores) --> [Aug25-->23:15 - Aug25-->16:27 - Last jobs! 280 cores]

• test2011-new Aug27-->16:45 ==> Aug28-->05:00

6.3. Matching

• Total time: 2,100 jobs (21 queries) x 30 mins/job --> 1,050 hours --> [Aug26--> 16:45 --> Aug26-->20:45 280 cores]

6.4. Ranking and Selecting for DPM

6.5. Running DPM

6.6. Fusion and Evaluation
