Quantization

This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each... Platforms: Matlab

Improved Gray Scale (IGS) codes are used for the elimination of false contouring in images, and image compression. This Python program generates the IGS codes for a set of input gray level values. Platforms: Windows, Mac, *nix, Python, BSD Solaris

In this program, MSE, Step size, Bit rate, Quantization Noise are also calculated Platforms: Matlab

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK.Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve.The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one)...

A true color image (24 bit image) usually contains thousands of unique colors. This program uses K-Mean algorithm to find out the significant colors in an image and represents the image with less number of colors.The colors present in the output image are exported as a CSV file. Platforms: Matlab

The purpose of the speech is communication. The area of speech processing is just developing, and shows the tremendous potentialities for widespread use in the future.In this project we have processed the speech signal with the help of the DIGITAL SIGNAL PROCESSING techniques. The speech signal... Platforms: Matlab

Writes 32-bit or 64-bit floating point audio data (single or double) to a .wav file at 8, 16, or 24 bits resolution, using rectangular (RPDF) dithering during quantization to reduce unpleasant audible quantization error. Calling syntax for this function is identical to MATLAB's wavwrite. Platforms: Matlab

FinalPlug is a professional peak limiter/volume maximizer with extensive bit depth truncation and dither options, making it ideally suited for a final mix. Tame the peaks a bit, or really squeeze all the volume you can out of it. The FinalPlug interface could hardly be simpler. Select a desired... Platforms: Mac
