Which kind of interpolation best for resizing image?

Question

I have a numpy array that I wish to resize using opencv. Its values range from 0 to 255. If I opt to use cv2.INTER_CUBIC, I may get values outside this range. This is undesirabl

Answer 1

I think you should start with INTER_LINEAR which is the default option for resize() function. It combines sufficiently good visual results with sufficiently good time performance (although it is not as fast as INTER_NEAREST). And it won't create those out-of-range values.
