Webb30 juli 2024 · One way of sharpening an image is doing this: Mat sharp; Mat sharpening_kernel = (Mat_(3, 3) << -1, -1, -1, -1, 9, -1, -1, -1, -1); filter2D(img, sharp, -1, sharpening_kernel); The sharpening strength depends on the values of the kernel which should sum up to 1). Another way is subtracting a smoothed image from its original:

If you’re interested in shrinking your image, INTER_AREA is the way to go for you.
