Convolution of 2 image

I am working on image processing. Especially Self - convolution descriptor.

Can anybody tell me what is the result after convolution of 2 image.

for example, I have a big image.(1000*1000) I choose a patch (5*5) and convolve this patch with all other patch of the big image. So what will I get?

thank you!!

See if the first half of this helps:

Convolution and filtering are equivalent if you invert the second image.

Dear Mr.Almet Cecen, Thank for your answer, Actually, I have already study about the filter and I have known that the result after filtering is an blurred image. In my case, I want to make a descriptor of that image to compare with other image. Do you have any idea?

Thank you!
