Exposes the MatConvNet C++ im2row function as a MATLAB function called vl_nnim2row.
The mex interface code was written by James Thewlis.
The easiest way to use this module is to install it with the vl_contrib
package manager. mcnIm2row can be installed with the following commands
from the root directory of your MatConvNet installation:
vl_contrib('install', 'mcnIm2row') ;
vl_contrib('compile', 'mcnIm2row') ;
vl_contrib('setup', 'mcnIm2row') ;
To understand the im2row function, see Section 6.1 of the MatConvNet manual. You can get some idea of the operation by examining the effect of im2row on example image (shown below for a kernel size of [20, 20]). This figure can be produced by running im2rowDemo.m.
