Clipping and Scaling
clip(M, [min, max])—Return vector or matrix M clipped to set limits.
scale(M, [min, max])—Return vector or matrix M scaled to set limits.
These functions scale an image's intensity levels to lie between the specified minimum and maximum, or truncate them to a minimum and maximum. It is often desirable to scale or clip a processed image to a standard grayscale range of 0 - 255.
The functions return another matrix, an image with the specified scaled or clipped intensity range.
M is an image vector or matrix.
min, max are optional and represent the lowest and highest values in the output intensity scale.
If min, max are not supplied, then they default to min = 0 and max = 255.
