High boost filtering matlab
Web1 Answer. i. 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.
