WitrynaAlgorithms The 'adaptive' method binarizes the image using a locally adaptive threshold. imbinarize computes a threshold for each pixel using the local mean intensity around the neighborhood of the pixel. This technique is also called Bradley's method [2]. Witryna14 sie 2024 · Accepted Answer imresize does not have or use any information about the size of the pixels. It combines the values of the pixels only to create a smaller or greater output array. If the resizing changes your "result", this must be an effect on how the "result" is calculated.
