Image detection problem using canny edge and Hough Transform

Hi,
I am novice in Matlab and image processing but I am working on detection of iris in a images, These Images are analysed by canny edge for detection of edges and iris and pupil are detected using circular hough transformation.
Most of the images are analysed with proper detection of iris and pupil while some of the images give wrong detection of iris and pupil in an image.
I am not sure where to start looking for the error.
Is there any possibly if I can get some advices where I must start looking for error.
Also please let me know how to upload the Image I am analysing.

canny edge detection and hough transform are very sensitive with illumination and colour diffusion,better not to use them for iris detection,they normally work for line or sharp edges,increasing threshold value might do something favourable.

By thresholding do you mean the radius range of pupil, iris which Libor has kept different for different databases in segmentiris.m?
