The following Matlab project contains the source code and Matlab examples used for block segmentation. Face feature can be extracted by block segmentation. Here image clustered into user input block size. Face feature (Eye, nose, etc.) can clustered by matrix separation. Block size can be varied by user interaction (bs_r and bs_c).
The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
