Response to the following problem:
The binary arithmetic coding approach specified in the JBIG standard can be used for coding gray-scale images via bit plane encoding. In bit plane encoding, we combine the most significant bits for each pixel into one bit plane, the next most significant bits into another bit plane, and so on. Use the function extrctb p to obtain eight bit planes for the sena . img and omaha. img test images, and encode them using arithmetic coding. Use the low-resolution contexts shown in Figure .
