I have a question on the imageDataAugmenter fuction provided on the matlab. i tried to rotate the original image for 45 degree and there are some black region that occur during the rotation. I have several confusion regarding the black region. Hope someone could help to clarify on the matter.
1. Does the black region affect the classification accuracy of CNN?
2. Would the CNN consider the black region of the rotated image as one the feature during the training?
3. Is there any way to prevent the black region?
