After taking the HOG of a whole image, and taking the HOG of a 32x32 section, comparing the same location from the whole image HOG and the 32x32 HOG they are not the same. Even in the areas in the middle of the image which are far from the borders.
What is the reason?
I am a research student. I would like to use your methodology (Color segmentation by Delta E color difference) for shade matching.
I just want to find where the reference shades (from a standard color chart)are located in the chosen image? Is it possible?
Plz help me
