13 Mar 2009 SPLINEFIT Fit a spline to noisy data. Author: Jonas Lundgren

for images, it's too slow, use better steepest descent. this figure isn't 'noisy' at all. try to pluck an image out of the 'dirt' where the SN is about 12dB

13 Mar 2009 Contrast Enhancement Utilities (Image Equalization, PDF, CDF) Histogram Processing Author: Javier Montoya

how are these any different that inbuit functions? there is already a histogram equalization function as well as adaptive histogram. code needs to be vectorized, get rid of loops and use LU or SVD decomp. doesn't handle uint16.

26 Feb 2009 Efficient subpixel image registration by cross-correlation Registers two images (2-D rigid translation) within a fraction of a pixel specified by the user. Author: Manuel Guizar

forgot to rate. wow this code is brutally fast and accurate, if you define a ROI even faster. this code needs some kind of award. how much faster would it be if it was compiled in to a mex?

works but i had to re=write code for UINT16 images, very fast and accurate. why are you using double? do you really need that accuracy in the dft?
