This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and the similarity invariants of trapezia can be linearly determined using some prior knowledge on the cameras or the trapezia. The proposed algorithms have wide applicability since parallel lines are not rare in many scenes. Experimental results validate the proposed approaches. This work presents a unifying framework based on the parallelism constraint, and the previous methods based on the parallelograms or the parallelepipeds can be integrated into this framework. Key words: invariant parallelism constraint camera calibration 3D reconstruction

Software Engineering and Computer Games By Rudy Rucker Software Engineering and Computer Games was written with four broad goals: To teach a lively style of object-oriented software engineering. To show how to bring a complete program to the level of a commercial release. To provide a "game engine" framework of linked classes for game development. To help students create computer games that are interactive, rapidly executing, and visually beautiful.

This my phd thesis for the WDM optical network optimization, which employs convex optimization techniques to solve the proposed integer problems. The computation complexity of my optimization framework is very low compared with other existing method and a performance bound is provided at the same time.

In this article, we present an overview of methods for sequential simulation from posterior distributions. These methods are of particular interest in Bayesian filtering for discrete time dynamic models that are typically nonlinear and non-Gaussian. A general importance sampling framework is developed that unifies many of the methods which have been proposed over the last few decades in several different scientific disciplines. Novel extensions to the existing methods are also proposed.We showin particular how to incorporate local linearisation methods similar to those which have previously been employed in the deterministic filtering literature these lead to very effective importance distributions. Furthermore we describe a method which uses Rao-Blackwellisation in order to take advantage of the analytic structure present in some important classes of state-space models. In a final section we develop algorithms for prediction, smoothing and evaluation of the likelihood in dynamic models.

《JavaServer Faces》 In JavaServer Faces, developers learn how to use the new JavaServer Faces framework to build real-world web applications. The book contains everything you ll need: how to construct the HTML on the front end how to create the user interface components that connect the front end to your business objects how to write a back-end that s JSF-friendly and how to create the deployment descriptors that tie everything together. This book is a complete guide to the crucial new JSF technology.

We present a particle filter construction for a system that exhibits time-scale separation. The separation of time-scales allows two simplifications that we exploit: i) The use of the averaging principle for the dimensional reduction of the system needed to solve for each particle and ii) the factorization of the transition probability which allows the Rao-Blackwellization of the filtering step. Both simplifications can be implemented using the coarse projective integration framework. The resulting particle filter is faster and has smaller variance than the particle filter based on the original system. The convergence of the new particle filter to the analytical filter for the original system is proved and some numerical results are provided.

JAVA項目開發實踐-網上范例4: 1:要完成本程序,首先需要安裝Java SDK,建立基本的java程序運行和編程環境; 2:安裝JMF(Java Media Framework)軟件;這很直觀,從Sun的網站下載相應的(這里是對應于windows平臺)安裝文件包jmf-2_1_1c-windows-i586.exe然后直接安裝即可。安裝過后,確認系統變量“CLASSPATH”包含包含JMF的sound.jar、jmf.jar;當然在上一步的SDK安裝中也需要確認相應的系統變量的值;這里不贅述了。 3:開始編制本實例的程序代碼;作者使用了eclipse開發源程序。如同在程序中看到的,程序頭包含的那些程序包是該工具自動識別加入的。實際上,讀者可以采用任意一種編輯器編輯源程序即可,編輯完成存儲為“ediaPlayer.java”源文件即可。 4:如上得到源文件后,開始編譯源文件;命令如下: javac MediaPlayer.java 編譯成功后,編譯器生成兩個.class文件:MediaPlayer.class,MediaPlayer$1.class。如果出現編譯錯誤,請檢查以下各項: 源代碼輸入是否正確無誤、CLASSPATH設置是否正確。 5:運行程序;接下來就可以執行“java MediaPlayer”命令啟動媒體播放器。

DataBurn is an Objective-C example which demonstrates some of the features of DRTracks. The sample illustrates how to create a DRFolder from an existing folder on the source disk and burn it to disc, creating a hybrid ISO9660/Joliet/HFS+ data CD. The sample also uses the DiscRecordingUI framework to present the standard burn setup and progress user interfaces.
