Phase Based Template Matching

Phase information is used for matching the input imagery with the template.

Description

Phase information is used for matching the input imagery with the template. Both the images are filtered with canny edge detector. The timing efficiency is introduced by implementing skipping steps while doing correlation. The advantage of Phase based correlation technique is that it shows good response against shift/brightness variation and noise addition i.e. salt & pepper/Gaussian noise [1,2]. Templates includes small portion of cropped from input imagery with gaussian noise introduced in them.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7 (R14)

It is a quite interesting work, though I do not know too much about matching image. It seems it is quite good. Thanks for sharing!

Hi Everyone,

This is great. But how do you detect facial features using template matching?

I'll be very grateful for your help. Thanks! :)

Really nice work.cheers

hi sir, template matching is superb. But how can i detect a face from a group of faces using template matching.please do the needful help. thank you.

is it possible to combine region of interest(roi) method in phase correlation?

Thanx for sharing your code. I am curious to know how can I detect same target but more than one in image.
