Bit Planes

A bit plane is of a image is a set of bits corresponding to a given bit position in each of the binary numbers representing the image .For example ,for 16-bit data representation there are 16 bit planes.The first bit contains the set of  most significant bit & the 16th bit contains the least significant bit.The first bit plane gives the roughest but the most critical approximation of values of a medium & the higher the no of bit planes,the less is its contribution to the final stage.Thus adding a bit plane gives a better approximation.Bit plane should not be confused by Bitmap because bit plane refers to the location of the data while bitmap refers to the data itself. In the bit plane replacement of most significant bit shows more distortion in than the distortion resulted by the replacement of least significant bit.Today ,I have done a program for creating bit planes of 24-bit color image.Here are input & output images of 24-bit color image:-

24-bit input image:-






24-bitplane output images:- 
Here we can see that bitplane of  24-bit image having more visible images than 8-bit & there is visible images for each RGB channels.
