Description

two functions used to implement template matching. the program finds the template image inside the target image using correlation.

Hello!this was quite useful to me. But the detection ends once it finds one instance. Is there a way to mark a rectangle over all the instances that it finds?

Hi there.

Can I ask how to implement this? When you say 2 functions are used, which 2? And you're trying to match image2 to image1? I have to match a scale marking in my image(scale is 10mm). So if i have an image of just the 10mm marking, i call it "image2" and then just rename my origional "image1"??

Sorry, little confused.

Cheers

one of the code in tmp.m file: M(i,j)=corr/sqrt(sum(sum(Nimage.^2))) that used for Nimage(target image) normalization, whether is it lack of a normalizated for image22(template image)? i modified M(i,j):M(i,j)=corr/sqre(sum(sum(Nimage.^2))) *sum(sum(image22.^2)))) , is it necessary?

Hi Everyone,

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

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