Answer 1

You can use:

image = cv2.copyMakeBorder( src, top, bottom, left, right, borderType)

where src is your source image and top, botto, left, right are paddings around the image.

You can use max(sizes) - size value of the image in a while loop to add the padding to each image. the bordertype can be one of these:

• cv2.BORDER_CONSTANT
• cv2.BORDER_REFLECT
• cv2.BORDER_REFLECT_101
• cv2.BORDER_DEFAULT
• cv2.BORDER_REPLICATE
• cv2.BORDER_WRAP
