I am writing this message for the third time. Hope that this time it is received by everyone in the group.
SO, I am working presently on HoS in Images. I am using the bispecd.m file from the HOSA toolbox. However I don't understand the use of the Hankel mask. Furthermore how do we find out the lag in frequencies used so that we can do a phase recovery from the bispectrum phase.

Thanks for helping
