WitrynaSimilar to the imresize function, the imresize (downsample) subsystem in this model supports two ways to define the output image size. You can specify a scale factor ranging from 1.000 to 127.999, or you can define the output frame width and height in pixels down to a minimum of 8 by 8. WitrynaFor example: imresize (im, 1); # return the same image as input imresize (im, 1.5); # return image 1.5 times larger imresize (im, 0.5); # return image with half the size imresize (im, 2); # return image with the double size imresize (im, [512 610]); # return image of size 512x610

The leftmost column, column 1, is the left-most quarter of the image. For example, if you're using the cameraman image with 256 columns, then column 1 of X is columns 1-64 of the cameraman image, I, all strung together in one big long column vector. diabetic chokecherry syrup
