Webexample B = 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 only resizes the first two dimensions. If scale is between 0 and 1, then B is smaller than A. Web2 Answers Sorted by: 8 "Bilinear interpolation" is an interpolation method. But downscaling an image is not necessarily only accomplished using interpolation. It is possible to simply resample the image as a lower sampling rate, using an interpolation method to compute new samples that don't coincide with old samples.

WebOct 9, 2024 · Applying an LPF before sampling is to prevent potential aliasing in the downsampled image. Aliasing can result in Moiré patterns in the downscaled image. It is probably called "area" because it (roughly) preserves the area ratio between the input and output shapes when averaging the input pixels.
