ABFilter library

version 0.1

This library is available in order to help the implementation of spatiotemporal filtering in video sequences. Specifically, this library implements the physiological plausible filters proposed by Adelson and Bergen (1985)(*).

The ABFilter library is based on the creation of entities that could be associated to neurons. Each entity is an ABFilter instance that has assigned a spatial location in the input video. Besides the spatial location, an ABFilter instance should also have associated a location in the spatial-temporal frequency space.

The library contains three directories containing:

How to generate the library

To generate de library, inside src folder, type:

 make lib 

How to compile

To compile the test file, inside src folder, type:

 make testABFilter 

How to run the test file

Library includes a video sequence in INR format (grating.inr) to test the filtering. You can modify the testABFilter code to load a list of images instead of a video sequence. To run the test file with the included video sequence, type for instance:

 ./testABFilter -i grating.inr -r 8 -ef 5 -xi 1 -omega 5 -orient 45
