In attach picture the pixel matrix D is written as an image but if i read the same image from the written one I found that all pixel values except zero are converted to 255. Why this is happening? Is there any solution to keep the pixel values same after writing it?

Hi Shamim, Try using this: imwrite(YourImage, 'YourFile.jpg', 'mode', 'lossless') if you want to write it as JPEG file.
Or you can use PNG or TIFF extension which are lossless compression standards.
