Answer:A
Which of the following operation is done on the pixels in sharpening the image, in the spatial domain?
A. Differentiation B. Median C. Integration D. Average
Explanation: We know that when we blur an image, we produce a pixel average, which might be termed integration. Because sharpening is the inverse of blurring, we may deduce that we sharpen the image by doing differentiation on the pixels.
