por

Synopsis

Description

por performs a bitwise "or" between values of the two inputs im_in1 and im_in2.

If inputs are integer images, the "or" operator uses the '|' C operator and is applied on each pixel:

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

For real images, the "or" operator is "+":

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

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

For graph, the "or" operator is "+" and it is applied on each node values.

For region map, the "or" operator is the union between regions. The result im_out is a new region map with regions of each input region maps, given preference to smaller regions.

The two inputs must be of the same type.

Inputs

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

Outputs

• im_out: an object of the same type as im_in1 and im_in2.

Result

Returns SUCCESS or FAILURE.

For region map, returns the new higher label value.

Examples

• Superposition of the boundaries of the tangram pieces onto the original image :

    pboundary 8 a.pan b.pan
    por examples/tangram.pan b.pan c.pan
