Composing multiple BW images to one color image

Composing n binary images to a colored image while each image is layer of some color.

Description

function [c_img] = RGB_layers(imgs,RGBs)

RGB_layers - Visualize n gray/binary images in pseudo color

INPUT: (imgs,RGBs)
  imgs: m*k*n matrix. imgs(:,:,i) is a grayscale/BW image.
  RGBs: n*3 matrix, each row represents what color the layer will be.
(Optional. By default it will be the jet colormap)

 OUTPUT: m*k*3 color image.

 EXAMPLE:

I=imread('cameraman.tif');
imgs(:,:,1)=I>180;
imgs(:,:,2)=I<70;
imgs(:,:,3)=mod(I,40)==0;
imgs(:,:,4)=mod(I,70)==0;

RGBs=[1,0,0;0,0.6,0;0,0,1;0.2,0,0.3];
c_img=RGB_layers(imgs,RGBs);
imshow(c_img);
