# Multiplication of RGB-Color Images

[Laboratory]

The multiplication of two RGB Images is a pointwise operation. Each pixel element of the RGB image is multiplied by the correspondent pixel coordinate/element of the other image. It is possible to get very unexpected results.

In this experiment, we are multiplying an RGB image by constant color planes.

Shown below is the original RGB image.

Original color image (RGB)

Multiplying by a weight of 1 in the Red Plane and 0 on the others:

a)weighted image (R=1,G=0,B=0); b)resultant image
a) | b)

Multiplying by a weight of 1 in the Green Plane and 0 on the others:

a)weighted image (R=0,G=1,B=0); b)resultant image
a) | b)

Multiplying by a weight of 1 in the Blue Plane and 0 on the others:

a)weighted image (R=0,G=0,B=1); b)resultant image
a) | b)

Multiplying by a weight of 0.8 in the Red Plane, 0.4 in the Green Plane and 0.3 in the Blue Plane:

a)weighted image (R=0.8,G=0.4,B=0.3); b)resultant image
a) | b)
