PANDORE Version 6 GREYC-IMAGE

pmean


Performs average between images or graphs.


Synopsis

pmean [-m mask] [im_in1|-] [im_in2|-] [im_out|-]

Description

pmean computes the average between the two inputs im_in1 and im_in2.

If inputs are image, the average is done on each pixel values:

   pixel(im_out) = ((pixel(im_in1) + pixel(im_in2))/2;

The two inputs must be of the same type.

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

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

Examples

Computes the mean between pixels of the two images a.pan and b.pan:

   pmean a.pan b.pan c.pan
