WebFirst we are importing the libraries required to perform sharpening on our image. OpenCV -> For operations on image. Numpy -> For performing fast matrix operations. cv2.imread -> To read the input image in the form of numpy array from our disk. cv2.resize -> To resize our image to fit in (400, 400) dimension. WebThis plugin-filter implements ImageJ's Unsharp Mask command. Unsharp masking subtracts a blurred copy of the image and rescales the image to obtain the same contrast of large (low-frequency) structures as in the input image. This is equivalent to adding a high-pass filtered image and thus sharpens the image.
