I have to extract LBP features from a rotated rectangle section of an image. Since the extractLBPFeatures function takes as an input a NxM matrix, I thought about rotating my image to get an axis aligned rectangle. In the case of the image below I still get slanted edges because parts of the rectangle are out of the image.
So I though about creating small axis aligned rectangular patches to cover the maximum possible area of the rotate rectangle. I wasn't able to find such an alghoritm. Do you know any implementations?
Do you have any other idea how to extract the LBP features from the rotated rectangle?
Thank you in advance!
