Transform Boundaries

This collection of M-files takes as input a close-up image of the human iris and returns as output the original image overlaid with circles corresponding to the pupil and iris boundaries.In addition it returns the centre and radius coordinates of both boundaries in the variables ci and cp.Notes...

the face is detected using haar transform and it is then given for tracking through the e cam window and can use for robotic s .shown in gui

The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear...
