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

These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, does not use multiple threads. This code requires JDK 1.1 or later, but can easily be adapted to JDK 1.0.

The GRLIB IP Library is an integrated set of reusable IP cores, designed for system-on-chip (SOC) development. The IP cores are centered around a common on-chip bus, and use a coherent method for simulation and synthesis. The library is vendor independent, with support for different CAD tools and target technologies. A unique plug&play method is used to configure and connect the IP cores without the need to modify any global resources.

xajax is an open source PHP libary for building Web-based Ajax applications. This wiki is a community-edited effort to generate information about and documentation for the xajax project. The base documentation and starter tutorials were written by the xajax authors, but please feel free to contribute to the discussion tabs for each page. Also, you are encouraged to add to the Tips and Tricks section with your own special xajax discoveries.

CFlowchartEditor is an extension of CDiagramEditor. CDiagramEditor is a vector editor, with a CWnd-derived window (CDiagramEditor), a data container (CDiagramEntityContainer) holding the draw-objects, undo stack and managing copy and paste, and objects derived from CDiagramEntity representing objects drawn on screen. CDiagramEditor lacks one feature (that is difficult to implement in both simple and general fashion) - links. Manually maintaining links in a - for example - flowchart or network topography map is unwieldy. Therefore, I ve created a reference implementation for one way of adding this functionality.

The subroutines glkern.f and lokern.f use an efficient and fast algorithm for automatically adaptive nonparametric regression estimation with a kernel method. Roughly speaking, the method performs a local averaging of the observations when estimating the regression function. Analogously, one can estimate derivatives of small order of the regression function.
