Represent the quantized indices using the run-length representation. That is, generate a series of symbols, the first being the quantized DC index, the following symbols each consisting of a length of zeros and the following non-zero index, the last symbol is EOB (end of block). c. Encode the DC index and the runlength symbols from (b) using the JPEG coding method, with the coding tables given in the lecture note. For this problem, assuming the quantized index for the DC coefficient of the previous block is 60. 4. Determine the Y,Cr,Cb values for a pixel with (R,G,B) value of R=200,G=150, B=50....
