Witryna1 mar 2024 · The command imresize (x,1/2) halves the image size. This is done by taking a matrix from the original matrix having elements whose row and column indices are even. imresize (x,2) means all the pixels are repeated to produce an image of the same size as original, but with half the resolution in each direction. WitrynaTools Partial plot of a discrete signal (black dots) and of its Lanczos interpolation (solid blue curve), with size parameter a equal to 1 (top), 2 (middle) and 3 (bottom). Also shown are two copies of the Lanczos kernel, shifted and scaled, corresponding to samples 4 and 11 (dashed curves).
