What's the code of this problem? in MATLAB

Decompose “picture.jpeg” into its bit planes, and then reconstruct the image using the two most significant bit planes. Compute the histogram by setting the least and most significant bits of each pixel of “picture_1+n.jpeg” to zero respectively. Your output should contain 8 diagrams, including the original and reconstructed images, the binary images of the least significant bit (LSB) and the most significant bit (MSB) planes, and the histograms and modified images by setting LSB=0 and MSB=0.
