WebThe graythresh function in MATLAB is used to determine the threshold level for a grayscale image, but it cannot be used directly on an indexed image. To use graythresh on an indexed image, you need to first convert the indexed image to a grayscale image. Here's an example of how to use graythresh on an indexed image in MATLAB:
