WitrynaB = imresize (A,scale) returns image B that is scale times the size of image A. The input image A can be a grayscale, RGB, binary, or categorical image. If A has more than two dimensions, then imresize … 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.
