i have question like u about CCOEFF algorithm in theory. do u know, what do x'' & y'' refers to ? i know x&y are coordinates for source image, x' & y' are coordinates for template.

what do x'' & y'' refers to ? i know x&y are coordinates for source image, x' & y' are coordinates for template.

i am looking for advanced user interface with open CV.

i have searched and got mostly using Qt, wx widgets, fltk but not with visual studio. i use visual studio as compiler, can i make UI by visual studio ? thank you.

that is what i want to know, the inside of cvMatchTemplate function does. that doesn't make sense me although the color isn't involved. color image that has 255 values compare with binary image that has only 2 values. it is still a mystery for a newbie like me.

thanks before for your answer, i really apreciate it. this is my problem, i have color image and binary template and it works. but, i don't understand how can it be.is the computation made channel by channel and the results are summed just like you said? because the template and the image are different. One is binary and the other is color.

Hello masters. i need ur help about template matching.

my basic question is what is 'single channel' mean ? is it mean grayscale so if we have a color image, the image has '3 - channel' (RGB) ? i just want to make it sure.

in cvMatchTemplate() function, should image and template in single channel ( single channel what i mean is grayscale ) ? because i have tested the function with color image and grayscale template and it works. the template is cropped from the image that had been converted to grayscale. my second and also last question, how is cvMatchTemplate function work when the image is color and the template is grayscale ? is the image converted to grayscale automatically ?

thank you.
