Simple Video Generators

Matlab apps to generate simple videos for imaging research articles.

Generate Movie Pair

Function

Tile two movie side by side or place single movie. Add frame stamps (frame-dependent labels) and legends (static labels) (as many as we want). Add color coding to frame.

Can be used for hyperspectral imaging data, time imaging data, z scanning data visualization.

Time lapse data

Comparison on video quality between methods.

Hyperspectral data

Scan through different wavelength with pseudo-color.

Installation

** Requires MATLAB 2020 or higher **

Open Matlab and double click the GenerateMoviePair.mlappinstall file. The app will be added to the APPS Tab in Matlab.

Usage

1. Select one/two movies (tif or tiff stack file) by clicking buttons Left Frame and Right Frame; If using only one movie, just leave one of the entries empty.
2. Choose Index Offset and Total frames;
3. Add time stamps and legends (if applicable) by clicking button Add beside their corresponding menu; Check color coding if applicable.
4. Preview by draging the Time slider;
5. Click on button Render. The movie will be saved in current folder.

Options

• Index Offset: The preview frame index will be the frame index in Time slider added by this Index Offset.
• Total frames: The total number of frames to be previewed and rendered.
• Adjust image contrast: Adjust Lower Clip and Upper Clip to clip the lower and upper intensity and stretch the histogram.
• Frame Stamps: Choose one frame stamps from the drop-down menu and edit its position X, Y, Size, Step, init and Unit. The frame stamp of a certain frame $i$ will be $Init + i * Step$ with the unit defined by Unit. The Step and Init can be negative.
• Legends: Similar to frame stamps, except that the text box defines the string to show as it is.

• [updated 8/15/2022] Color coding: Check Enable Color Coding to add color to each frame. The hue applied to each frame will be interpolated from the Hue at the beginning to Hue at the end.
