- spiht algoritm based image compression
- License: Freeware
- Price: 0.00

The SPIHT method is not a simple extension of traditional methods for image compression, and represents an important advance in the field. The method deserves special attention because it provides the following: Highest Image Quality Progressive image transmission Fully embedded coded file Simple quantization algorithm Fast coding/decoding Completely adaptive Lossless compression Exact bit rate coding Error protection Encoding/Decoding Speed The SPIHT process represents a very effective form of entropy-coding.

In this document I show how to verify the functionality of your DSP code via processor in-the-loop (PIL) co-simulation using Simulink?s UDP (user datagram protocol) blocks. These blocks are a new addition to the R2006b release of Simulink. This example is an extension of a previous example which was based on using Texas Instrument?s RTDX (real-time data exchange) instead of UDP.
