You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. codebook for one period of a sinusoidal signal, starting from a rough initial mx = max (abs (x)); mx is defined because in order to use floor we need to scale the x. q256 = mx* (1/128)*floor (128* (x/mx)); mx shows the maximum value for x so x / mx will take values over [-1 1] and 128*x/mx over [-128 128] will cover all 256 levels. Question 1: why we should multiply the sample,y(i), with by 2^(b-1) , and then round it to get the quantized value? But if you multiply 3/8 by 2^2 (4) and then round you will get round(3/2) = 2. % Compare mean square distortions from initial and optimized, % Times at which to sample the sine function, Determine Which Interval Each Input Is In.

Ebook link - https://www.academia.edu/36135973/Book_Modern_Digital_And_Analog_Communication_Systems_4th_edition_by_Lathi, In sigp, you are measuring how much steps of Delta it takes to go from sig_nmax till your input signal at the point (sig_in). To quantize these values to a bit depth of b, you can do the following: If we want to zoom in on the first, say, 500 values, we can do so with. A quantization partition defines several contiguous, nonoverlapping appropriate partition and codebook parameters. My code untill now : N = 10; K=7; I=imread ('baboon.bmp'); Idouble = double (I); mat=zeros (size (I,1)*size (I,2),size (I,3)); R=I (:,:,1); G=I (:,:,2); B=I (:,:,3); mat (:,1)=R (:); mat (:,2)=G (:); mat (:,3)=B (:); [IDX,CENTERS] = kmeans (mat,N); Perform quantization on the sampled data.
