I want to calculate the distance between each block centered at (xi, yi) and the centroid of fingerprint image located at (xc, yc). Anyone has an example code?
For example, a fingerprint image of 300*480 is divided into blocks of 16*16. One can do a block operation with blkproc, but how can calculate the global centroid of each block when using blkproc. Or other way to do this. Thanks.
