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

Each arc of a binary-state network has good/bad states. The system reliability, the probability that source s communicates with sink t, can be computed in terms of minimal paths (MPs). An MP is an ordered sequence of arcs from s to t that has no cycle. Note that a minimal path is different from the so-called minimum path. The latter is a path with minimum cost.

This package consists of the executable (UCW), a default script file, this file, and the library files. It is important that the header files end up in a include subdirectory of the directory where UCW is found. If you unzip this file using its path information ( use folder names ) this will automatically happen. You can optionally specify the UnderC directory with the environment variable UC_HOME note that this points to the directory containing ucw.exe. If you do this, then you can copy the executable anywhere and it will still be able to find the header files.

This manual describes the Call Library Function Node and the Code Interface Node (CIN). The Call Library Function Node and the CIN are the LabVIEW programming objects you use to call compiled code from text-based programming languages. This manual includes reference information about libraries of functions, memory and file manipulation routines, and diagnostic routines that you can use with calls to external code.
