Document Content and Description Below

Stevens Institute of Technology Department of Electrical and Computer Engineering CpE 462 Introduction to Image Processing Homework 8: 8.1 Quantization and Huffman coding 8.1.1 Use a 5-level unif ... orm scalar quantizer as shown to quantize the sample sequence {0.25, -1.10, -0.15, 2.35, -1.40, 0.10, 0.90, -0.05}. Provide the output sequence. The quantization output: {0, -1, 0, 2, -1, 0, 1, 0} 8.1.2 Design the best fixed-length code for the outputs of this quantizer, i.e. for an alphabet A={2.0, 1.0, 0.0, -1.0, -2.0}. Then encode the quantization output sequence from 8.1.1 using this code. A fixed length code for alphabet A (need at least 3 bits for each codeword): 2.0 000 1.0 001 0.0 010 -1.0 011 -2.0 100 Then the coded output from 8.1.1 is {010, 011, 010, 000, 011, 010, 00 [Show More]
