I'm working on some image processing and try to reproduce something from an article, in which they integrate over an 2D image. I'm familiar with with finding the derivative of an image with the help of for example Sobel masking, but is there any procedure you would recommend for integration?
The problem I'm trying to work out is the following:
in which H is a vector with an x and y component. Or to put it differently, I've got to 2D images for H: Hx and Hy. I need to integrate both of them over x and y, to obtain the following:
Anyone any suggestions how to achieve this? I was already looking into the integralImage function, but was questioning if this was what I needed.
Thanks in advance! Cheers Koen
