Digital Image Processing Image Compression

Understand the two criteria that all coding mechanisms should satisfy. Understand Huffman coding How do you explain the average coding length from Huffman coding is always greater than the entropy? What image format uses which coding scheme?

Understand RLC, differential coding. In most images, certain gray levels are more probable than others. Include spatial redundancy, geometric redundancy, interframe redundancy. Certain information simply has less relative importance than other information in normal visual processing In general, an observer searches for distinguishing features such as edges or textural regions and mentally combines them into recognizable groupings.

What happens if the events are equally probable? Data and information Data is not the same thing as information. Data is the means with which information is expressed. Image Enhancement To process an image so that the result is more suitable than the original image for a specific application.
