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 .

Returns weighted percentiles of a sample given the weight vector w ％ The idea is to give more emphasis in some examples of data as compared to ％ others by giving more weight. For example, we could give lower weights to ％ the outliers. ％ The motivation to write this function is to compute percentiles for Monte ％ Carlos simulations where some simulations are very bad (in terms of goodness ％ of fit between simulated and actual value) than the others and to give ％ the lower weights based on some goodness of fit criteria.

用分支限界法求解背包问题（0/1背包） 1.问题描述：已知有N个物品和一个可以容纳TOT重量的背包，每种物品I的重量为Weight，价值为value。一个只能全放入或者不放入，求解如何放入物品，可以使背包里的物品的总价值最大。 2.设计思想与分析：对物品的选取与否构成一棵解树，左子树表示装入，右表示不装入，通过检索问题的解树得出最优解，并用结点上界杀死不符合要求的结点。

Synthesizable FIFO Model This example describes a synthesizable implementation of a FIFO. The FIFO depth and FIFO width in bits can be modified by simply changing the value of two parameters, `FWIDTH and `FDEPTH. For this example, the FIFO depth is 4 and the FIFO width is 32 bits.

map identification laquo yuan Problem description : the digital image processing of an image often expressed as a macute M pixel matrix. Each pixel value is 0 or 1. The value of 0 pixel image, said background, and the value of a pixel image, said a map of a million, usually called map million pixels. When a pixel in another pixels above, below, left or right, said that two adjacent pixels of the pixel. An image of the pixels belonging to the same map yuan, instead of adjacent pixels belonging to different map yuan. Figure yuan identification of problems is right for the given image pixel map marking yuan, making the same map billion yuan pixel map of the same markings and different map billion yuan pixel map of their marks are different.

This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems. The first three editions of Programming the Finite Element Method established themselves as an authority in this area. This fully revised 4th edition includes completely rewritten programmes with a unique description and list of parallel versions of programmes in Fortran 90. The Fortran programmes and subroutines described in the text will be made available on the Internet via anonymous ftp, further adding to the value of this title.

This document represents the first stage in a process of taking the National Strategy for Police Information Systems (NSPIS) forward. It defines the mechanisms to ensure that we (and our partners) have access to the right information, in the right form, in the right time at an appropriate cost. The Strategy will ensure the Police Service has a collective understanding of the value of information and that we are able to exploit National Information Assets in support of local policing.

Data mining (DM) is the extraction of hidden predictive information from large databases (DBs). With the automatic discovery of knowledge implicit within DBs, DM uses sophisticated statistical analysis and modeling techniques to uncover patterns and relationships hidden in organizational DBs. Over the last 40 years, the tools and techniques to process structured information have continued to evolve from DBs to data warehousing (DW) to DM. DW applications have become business-critical. DM can extract even more value out of these huge repositories of information.
