说明: 很有意思的图像隐藏程序。将几幅小图像隐藏在一幅大图像下面,并可以将源图像还原。
(Embed/Hide one or more images inside one bigger image (source image).
Code also tells how much of the source image you are using for embedding and as long as it s less than 100 percent, you can obviously cramp in more images.

For demo purposes, run:
>> hide_image('pano.jpg','map1.bmp','faces.bmp','house.jpg');
>> extract_image('embedded.png');
Works for gray and colored images.
Haven't tried various image formats, but it does work for jpeg, png and bitmap images.
specifications:
1. Number of input images to be hidden limited to 255.
2. Input images must have row size(height of image) less than 32767 and column size(length of image) less than 65535.
