Unsharp Masking and High-boost Filtering: • Blurring is first applied to the image with a specified kernel size, and then, create a mask by subtracting the real image with the blurred filter, then, add the real image to a variable K and multiply by the mask to sharpen the image. Where K >= 1, and for K > 1 is for High-boosting. 4.

High-boost filter is a sharpening second order derivative filter. ii. High-boost filter image is obtained by subtracting LPF image from the scaled input image. where k is any positive scaling factor. For k-1, HBF image = HPF image, therefore for HBF image k > 1 let us derive HBF mask by considering a digital image F.
