I have a task where I should count numbers of suits(diamonds, clubs, ...) in a set of playing cards image. I have created a template sub-image for diamond from my original image for example, using imcrop in Matlab. I have also converted both Original or target Image in grayscale. I'm trying to find the match of the sub-image in the target image and counts the corresponding diamonds in the target image.
Does anyone have a suggestion?
I try to use normxcorr2 I got a plot where I can see the area with highest peak, but I don't have any ideas how to compute this.
Any suggestions of algorithms.
