#### Topic: statistical correlator

I am comparing results from IMCORR and COSI-Corr's statistical correlator from a pair of Landsat 5 images. The two give different results using similar parameters. Via the published literature I understand quite well how IMCORR works, but I have found nothing describing how COSI-Corr's statistical correlator works, so I cannot explain why they give differing results. Can anyone tell me if COSI-Corr's statistical correlator uses the same algorithm as IMCORR, and/or if COSI-Corr calculates the peak of the correlation differently than IMCORR? This may help explain the differences in the results between the two feature tracking programs.

Thanks in advance,

Jamie
