直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit,并将秘密图像提取出来，最后显示。要求载体图像的大小大于等于秘密图像的大小，且秘密图像是二值或灰度图像(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low 4bit, and extracted secret image, the final show. Required size of the image carrier is greater than equal to the size of the secret image, and the secret image is a binary or gray image)
