Quantization

Uniform quantization in matlab

The following Matlab project contains the source code and Matlab examples used for uniform quantization. This MATLAB exercise illustrates the process of uniform quantization of a speech sample using a range of B-bits per sample, and displays the unquantized signal, the quantized signal and the error signal at the selected bit rate along with plots of signal and error power density spectrum, and the histogram of the quantization error signal.

Hierarchical rgb image compression with gui in matlab

The following Matlab project contains the source code and Matlab examples used for hierarchical rgb image compression with gui. The code performs the following operations: 1. DCT and Quantization on luma an crome components. 2. Zigzag scaning followed by encoding and decoding 3. Inverse DCT and Quantization. To run the code: Just run the file hierarchical.m and it will the gui.
