pmask

Synopsis

Description

pmask applies the mask im_in2 on the input im_in1.

For image, masking is applied on each pixel:

   if pixel(im_in2)
      pixel(im_out) = pixel(im_in1)
   else
      pixel(im_out) = 0

For color or multispectral image, the "mask" operator is computed separately on each band.

For graph, masking is applied on each node value.

For region map, masking is applied on label. All masked label are set to 0 in the result, and other labels are copied onto the output im_out.

Inputs

• im_in1: an image, a graph or a region map.
• im_in2: a gray level image or a region map.

Outputs

• im_out: an object of the same type as im_in1.

Result

Returns SUCCESS or FAILURE.

Examples

• Selection of the pixels inside the tangram pieces:

    pand examples/tangram.pan a.pan b.pan
