And using Huffman code, the message S is encoded
The result is: 0110010001110100010011
Find the message S by decoding the above result.
B: if you have the original image (2*2)
And using one of compression method we get the compressed image
Find (RMSE) to measure compression method.

Q2 A: one of the RLE types is: A group of m pixels that are all different is preceded by a byte with the negative value -m.by this method encode the following 8-bit grayscale bitmap: 12, 12, 12, 12, 12, 12, 12, 12, 12, 35, 76, 112, 67, 87, 87, 87, 5, 5, 5, 5, 5, 5
B: from below probabilities find Entropy
Q3: A:define the following:
1. quantization stage 2. the peak signal-to-noise ratio
B: one question about compression algorithms is how does one judge the quality of one versus another. In the case of lossless compression.
