What is in BasicVideoTools?

BasicVideoTools is a Matlab/Octave Toolbox intendend to deal with video data and spatio-temporal vision models. In particular, it includes convenient *.m files to:

• Read standard (VQEG and LIVE) video data
• Rearrange video data (as for instance to perform statistical analysis)
• Generate controlled sequences (controlled contrast, texture, and 2d and 3d speed)
• Compute 3D Fourier transforms
• Play with motion perception models (spatial texture and motion-sensitive cells of LGN, V1 and MT, and spatio-temporal CSF)
• Visualize movies (achromatic only)

What is not in BasicVideoTools?

BasicVideoTools does not include:

• Optical flow or motion estimation/compensation algorithms

• Video Coding algorithms

• Video Quality Mesures

  If you are looking for the above, please consider downloading other Toolboxes:

• Motion estimation:

  • Video_coding.html (Hierarchical Block Matching)

• Video Coding (improved MPEG)

• Video Quality

Download BasicVideoTools!

• The code (version 1.0. Use this version only for compatibility with the code in the experiments of the motion-aftereffect paper).

• The code (version 3.0 -Not only improved sampling functions and additional motion sensitive cells, but also more things)

• Optional data (not necessary to run the code): If you use these data please cite the VQEG and LIVE databases (for video), and the CVC Barcelona Database (for images)

  • Image data (1.8 GB). Luminance images from the CVC Barcelona Calibrated Image Database.

  • Video data (2.6 GB): Raw videos from the VQEG and LIVE video databases.

Installation and Requirements

• Download the BasicVideoTools file(s)
• Decompress at your machine in the folder BasicVideoTools (no location restrictions for this folder)
• Update the matlab/octave path including all subfolders
• Tested on Matlab 2006b and posterior Matlab versions

• Video and image data are only required if you want to gather statistics from natural videos or from natural images with controlled speed

How to get started?

For a general overview please take a look at the contents.m file, or (after you included it in th path) just look for help by typing the name of the folder, for instance: help BasicVideoTools_v2.

For additional details on how to use the functions in practice, see the demos:

• demo_motion_programs, demo on how to use most functions (except random dots and newtonian sequences).
• example_random_dots_sequence, demo on random dots sequences with controlled flow.
• example_newtonian_sequence, demo on physics-controlled sequences.
