pmult

Synopsis

Description

pmult performs the multiplication of the two inputs im_in1 and im_in2.

If im_in1 and im_in2 are images then the new image im_out is built with the multiplication of each pixel:

pixel(im_out) = (pixel(im_in1) * pixel(im_in2));

The two inputs must be of the same type.

The output type im_out depends on input type:

• Long if inputs are Uchar images.
• Long if inputs are Long images.
• Float if inputs are Float images.

For color or multispectral image, the multiplication is computed separately on each band.

If im_in1 and im_in2 are graphs then the new graph im_out is built with the multiplication of each node values.

Inputs

• im_in1: an image or a graph.
• im_in2: an image or a graph.

Outputs

• im_out: an image or a graph.

Result

Returns SUCCESS or FAILURE.
