// // Histogram Sample // This sample shows how to use the Sample Grabber filter for video image processing. // Conceptual background: // A histogram is just a frequency count of every pixel value in the image. // There are various well-known mathematical operations that you can perform on an image // using histograms, to enhance the image, etc. // Histogram stretch (aka automatic gain control): // Stretches the image histogram to fill the entire range of values. This is a "point operation," // meaning each pixel is scaled to a new value, without examining the neighboring pixels. The // histogram stretch does not actually require you to calculate the full histogram. The scaling factor // is calculated from the minimum and maximum values in the image.

WindML3.0补丁 WIND MEDIA LIBRARY 3.0.3 (CP3) for Tornado 2.2.0 and Tornado 2.2.1 Up-to-date product bulletins, information on known problems and fixes/changes made in this release, and essential reference documentation can be obtained from the Wind River Online Support web site. Installation: ----------------- The WIND MEDIA LIBRARY 3.0.3 supplement identifies the process to install WIND MEDIA LIBRARY 3.0.3. This is a not a complete WIND MEDIA LIBRARY 3.0 product and hence it is necessary that WIND MEDIA LIBRARY (aka WindML) 3.0 be installed prior to the installation of this product.

I ve written some many years ago dynamic Huffman algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. Huffman coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.

我所采用的内存管理思想是链表管理思想,内存分配方案是最佳适应方案(best fit)。其主要的数据结构为 struct node { char* p int memosize int flag struct node* next } 这是一个链表的结点的数据结构,用它来管理内存的分配与回收。P 表示所指的分配的内存的首地址,memosize 表示分配的内存块的大小,flag 为一个标志量,表示内存块是否被占用。用 1 和 0 来表示被占用和不被占用。next 表示下一个结点的首地址。 内存管理包括一个分配内存的mm_request(unsigned int)函数,一个初始化所要管理的内存的mm_init()函数,一个空闲列表排序函数sort(),一个释放内存的mm_release(void* )函数和一个判断内存是否被占用的IsFree(int)函数。

The purpose of this Primer is to help you begin to use MATLAB. It is not intended to be a substitute for the online help facility or the MATLAB documentation (such as Getting Started with MATLAB, available in printed form and online). The Primer can best be used hands-on. You are encouraged to work at the computer as you read the Primer and freely experiment with the examples. This Primer, along with the online help facility, usually suffices for students in a class requiring the use of MATLAB.

mastering dojo The book really rolls out the red carpet for Dojo to emerge with guns blazing! The authors show you how easy it is to use impressive widgets without installing a thing. I was amazed to discover that JavaScript is not just a toy language, how Dojo is built on top of it, and how both are invaluable in any web development project. Buy this book. It’s the next best thing to having the authors working at your side.

The tca package is a Matlab program that implements the tree-dependent component analysis (TCA) algorithms that extends the independent component analysis (ICA), where instead of looking for a linear transform that makes the data components independent, we are looking for components that can be best fitted in a tree structured graphical model. The TCA model can be applied in any situation where the data can be assumed to have been transformed by an unknown linear transformation.
