This tool enables you to isolate features in an image and to suppress image areas not of interest using a mask image.

Parameter

Description

Input

The input image from which you wish to isolate features or suppress areas not of interest.

Mask

The mask image that is applied to the input image.

The mask is laid on top of the input image. Image regions of the input image in1 where the mask is white remain unchanged, image regions where the mask is black are blacked out and suppressed.

Both images are aligned at the upper left corner. If the mask image is smaller than the input image in1, the mask is applied only to part of the input image, beginning at the upper left corner. The rest of the input image remains unchanged.
