Please help me.I'm implementing code by Libor Masek. I'm not getting correct boundaries for iris and pupil.I'm confused which values I've to use for lower&upper values for iris and pupil radius and lower &upper threshold values for hysterisis thresholding to mark edges.My input image is eye image(CASIA)is of 300*400 size.I'm using hough transform to find circles.I'm using lower&upper radius values for iris 28,75 and for pupil 8,15 respectively.Lower&upper threshold values 0.19&0.20 resp.Scaling factor 0.3.
I believe there is a bug in this code. If you change the line in demo.m, to display the error between the filtered and original images, i.e. from:
There is a clear bias/issue with the lower left hand quadrant edges, but not with the upper right hand quadrant edges.
