This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture Quality),
bit ratio etc. To get pq install pqs function .

The ImageHTML converts images to ASCII characters in HTML format.
The output image is in three formats: true color, grayscale, and
mono color.
The ImageHTML is provided "AS IS " without any warranty of any
kind, either express or implied. The entire risk as to the Quality
and performance of the software is with you. The author is not
liable for any damages resulting from the use and misuse of the
software.
The ImageHTML is freeware. You may copy it as long as you copy all
of files.
Developing internationalized products is a continuous balancing act. Developers and their managers often grossly underestimate the level of effort and attention to detail required to create either a world-ready, single-binary application ready for use in many different markets, or high-Quality, foreign-language editions of a product. If you are a developer, make sure your management understands what is involved.

Express DSP compliant C55x DTMF detector software is proposed in two versions: one with a 5 ms frame
size and one with a 10 ms frame size. The versions are quite similar in behavior. The version with a 10 ms
frame size is faster, but the overall Quality is higher in the 5 ms version, due to lower time granularity. DTMF算法for TI DSP 54X/55X

Make your graphics look better with an easy-to-use
JPEG 2000 decoding component. J2K-Codec can help
game developers, screensaver creators and many
others to improve their products--to achieve better
image Quality and reduce installation package size.
The new image compression standard based on wavelet
technology has many interesting features not
available in the old JPEG, such as alpha-channel
and varied resolution levels.
Uniform random number generators
by Agner Fog, 2001 - 2007
randomc.zip contains a C++ class library of uniform random number generators of good Quality.
The random number generators found in standard libraries are often of a poor Quality, insufficient for large Monte Carlo calculations. This C++ implementation provides random number generators of a much better Quality: Better randomness, higher resolution, and longer cycle lengths.
The same random number generators are available as libraries coded in assembly language for higher speed. These libraries can be linked into projects coded in other programming languages under Windows, Linux, BSD, etc. The library files are available in the archive asmlib.zip.
Non-uniform random number generators are provided in stocc.zip.
Testbenches have become an integral part of the design process, enabling you to verify that
your HDL model is sufficiently tested before implementing your design and helping you automate
the design verification process. It is essential, therefore, that you have confidence your
testbench is thoroughly exercising your design. Collecting code coverage statistics during simulation
helps to ensure the Quality and thoroughness of your tests.
A major goal of this book is to show to make devices that are inherently reliable by design. While a lot of attention has been given to “Quality improvement,” the majority of the emphasis has been placed on the processes that occur after the design of a product is complete. Design deficiencies are a significant problem, and can be exceedingly difficult to identify in the field. These types of Quality problems can be addressed in the design phase with relatively little effort, and with far less expense than will be incurred later in the process. Unfortunately, there are many hardware designers and organizations that, for various reasons, do not understand the significance and expense of an unreliable design. The design methodology presented in this text is intended to address this problem.
