16 Feb 2012 Scalable MPEG compression based on DCT coefficients This application makes 2 layers base Layer and enhancement layer from quantized coefficients Author: Zahid Ali

1. I have generated a movie using following code, (which is the input file):
for mj = 1:49
surf(sin(2*pi*mj/20)*Z,Z)
F(mj) = getframe;
end

when I run main.m from 'thresholdcoding' and play the output file(movie), it is alternate black and white frames. Why does the decoded output file does not look same as the input file?
2. GOP output is dim x dim x 3 and decoded output is dim x dim. Hence in shattest1.m, in 'edge', dim error appears. How to solve?
3. I want to put these two layers on a transmission channel. Am I right if i map 'X' & 'B' directly on a constellation?
