Hi, All,
I had the same segment fault problem. But I found after did
the following it worked:
==================================
At the bottom of the file, in function void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { },
REMOVE this line:
pTranslate = (double *)mxGetPr(prhs[2]);

We ONLY have 2 input parameters. prhs is the array of pointers to the input mxArrays. The above line read the
third parameter and caused segment faults.

After remove the line, I compiled with Open Watcom 1.9
in Matlab Version 7.8.0.347(R2009a) 32-bit edition.
It worked nicely.

My way to fix this code:
1. when input image size<256, error occurs...
you can change 256 in the for loops to nX or nY
2. when image size is too small, registration accuracy gets worse..
when image size is too small. the 256-bin histogram gets less samples. We can use less intensity bins, say, change from uint8 (0-255) to(0-80).
