IEEE Std 1180-1990. IEEE Standard Specifications for the Implementations of 8x8 Inverse Discrete Cosine Transform, specifies the numerical characteristics of the 8x8 inverse discrete cosine transform (IDCT) for use in visual telephony and similar applications where the 8x8 IDCT results are used in a reconstruction loop. The specifications ensure the compatibility between different implementations of the IDCT.
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
The algorm of viterbi. You talk to your friend three days in a row and discover that on the first day he went for a walk, on the second day he went shopping, and on the third day he cleaned his apartment. You have two questions: What is the overall probability of this sequence of observations? And what is the most likely sequence of rainy/sunny days that would explain these observations? The first question is answered by the forward algorithm the second question is answered by the Viterbi algorithm. These two algorithms are structurally so similar (in fact, they are both instances of the same abstract algorithm) that they can be implemented in a single function:
中心點漂移是一種非監督聚類算法（與k-means算法相似，但應用范圍更廣些),可用于圖像分割，基于Matlab實現的源碼。
MedoidShift is a unsupervised clustering algorithm(similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.
IDE開發環境，可以掛載SDCC
The BASIC IDE is a new, RAD (Rapid Application Development) IDE (Integrated Development Environment) for the RapidQ programming language. The IDE currently has rich project options, a form designer (similar to Delphi s), and code editor. The BASIC IDE is being coded in Borland® Delphi® . We are currently using Delphi 6, but you should be able to use Delphi 3 or later (Delphi 7 included).
Some of the BASIC IDEs features include:
Form Designer with support for all of RapidQ s components Flexible Code Editor Project Management Written in OO (Object Oriented) Delphi. Some future items that we are working on are:
Code Tip Code Completion CVS Integration Code Editor Macros Point-and-Click access to subroutines, functions, and variables
This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The
file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to
"capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2.
All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.

contains the following:
* The acdc algorithm for finding the
approximate general (non-orthogonal)
joint diagonalizer (in the direct Least Squares sense) of a set of Hermitian matrices.
[acdc.m]
* The acdc algorithm for finding the
same for a set of Symmetric matrices.
[acdc_sym.m](note that for real-valued matrices the Hermitian and Symmetric cases are similar however, in such cases the Hermitian version
[acdc.m], rather than the Symmetric version[acdc_sym] is preferable.
* A function that finds an initial guess
for acdc by applying hard-whitening
followed by Cardoso s orthogonal joint
diagonalizer. Note that acdc may also
be called without an initial guess,
in which case the initial guess is set by default to the identity matrix.
The m-file includes the joint_diag
function (by Cardoso) for performing
the orthogonal part.

A java GUI interface program used to download a batch of files in a specified URL, or a kind of similar files like pic01, pic02, pic03, ..., pic99, etc. And it can download all the links of index.html automatically.
A class--the basic building block of an object-oriented language such as Java--is a template that describes the data and behavior associated with instances of that class. When you instantiate a class you create an object that looks and feels like other instances of the same class. The data associated with a class or object is stored in variables the behavior associated with a class or object is implemented with methods. Methods are similar to the functions or procedures in procedural languages such as C.
