Hello, I'm sorry if this is not the proper place to post this , but I have a question and I hope some of you may be able to help me, so here goes: I need to apply a gaussian high pass filter on a grayscale image represented as a pixel matrix. After doing some reading I understand that I need to a pply a transformation matrix on each pixel of the image, actually a transformation vector in two passes, once for the x axis and once for the y axis resulting in something like(for a row, for example):
transofrmationSum = the sum of the transformationVector elements for (i=0, i<pixels.size; i++) { for (j=0, j<tranformationVector.size; j++) { pixels[i] = pixels[i] + pixels[i+(j-transformationVector.size/2)]*transformationVector[j]/transformationSum } } Please tell me if this is correct and how do I compute the transormation matrix for the gaussian high pass filter. Thank you, Daniel
