) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.

Exceptional C++ shows by example how to go about solid software engineering. Along with a lot of other material, this book includes expanded versions of the first 30 issues of the popular Internet C++ feature Guru of the Week (or, in its short form, GotW), a series of self-contained C++ engineering problems and solutions that illustrate specific design and coding techniques.

During the past four years, most of our research activities have been focused on image but also video and 3-D objects processing for security applications (watermarking and biometrics) and communications (talking heads, interfaces), with a special emphasis on facial images. More about our work can be found at http://www.eurecom.fr/~image. Our research activities are conducted with the backing of several industrials, in particular France Telecom Research and STMicroelectronics. For the past few years, we have had a regular scientific collaboration on Fractal Image Coding, Watermarking and Biometrics with the University of California, Santa Barbara (UCSB), in particular with Prof. K. Ros

Objectives The purpose of this notebook is to give you a brief introduction to the DiscreteWavelets Toolbox and show you how to use it to load images. Some basic image manipulation is illustrated as well. You will also learn how to use measures and tools such as cumulative energy, entropy, PSNR, and Huffman coding. Help on the DiscreteWavelets Toolbox Help for the toolbox is available by clicking on Help and then Product Help (or press F1) and then clicking on the DiscreteWavelets Toolbox. Several demos and examples are available as well by clicking on the Demos tab on the Help menu. Image Basics The DiscreteWavelets Toolbox comes with 18 grayscale images and 9 color images for you to use. There are three functions available to tell you more about these images. The first function is called |ImageList|. This function can tell you the names and sizes of the digital images in the Toolbox.

The emphasis of this book is on real-time application of Synopsys tools, used to combat various problems seen at VDSM geometries. Readers will be exposed to an effective design methodology for handling complex, submicron ASIC designs. Significance is placed on HDL coding styles, synthesis and optimization, dynamic simulation, formal verification, DFT scan insertion, links to layout, physical synthesis, and static timing analysis. At each step, problems related to each phase of the design flow are identified, with solutions and work-around described in detail. In addition, crucial issues related to layout, which includes clock tree synthesis and back-end integration (links to layout) are also discussed at length. Furthermore, the book contains in-depth discussions on the basics of Synopsys technology libraries and HDL coding styles, targeted towards optimal synthesis solution.

Designing a synchronous finite state machine (FSM) is a common task for a digital logic engineer. This paper discusses a variety of issues regarding FSM design using Synopsys Design Compiler. Verilog and VHDL coding styles are presented, and different methodologies are compared using real-world examples.

VideoMan (Video Manager) is an open-source C++ library that helps you developing video based applications. We created VideoMan to increase our productivity developing computer vision applications, but it can be used in many other ways. With VideoMan is very easy and fast to initialize any kind of video input like webcams, video files, frame grabbers, IEEE 1394 cameras and so on. You can initialize multiple inputs at the same time and show them in the screen. Also, you can show the results of the processing steps of your computer vision algorithm (extracted edges, back projections, detected blobs...) This way you can see the results of what are you coding, checking the results of your algorithm steps. Moreover, the implemented visualization scheme make easier to combine computer graphics with video, for example to show a 3d model on top of video for augmented reality applications.
