Automatic polygon layers integration and its implementation

Design and implementation of an automatic car turning system

In this paper, a control system is designed for automatic car turning. At first, the necessary information of car turning that were collected from the traffic bylaw, car driving training centers and traffic police are explained. Then, car turning is studied experimentally on several streets with different widths. Afterward, a proper path is designed for the automatic car turning system consider...

Integration of QoS Guarantees into SMIL and its Flexible Implementation

In this paper, we propose a flexible implementation technique for integrating QoS guarantee facilities into SMIL language. In the proposed technique, we use a subclass of E-LOTOS (called real-time LOTOS) as an intermediate language since it can nicely treat timing constraints for actions and synchronization among parallel processes used in SMIL documents. We implement QoS control mechanisms usi...

Automatic Color Enhancement (ACE) and its Fast Implementation

Automatic Color Enhancement “ACE” is an effective method for color image enhancement introduced by Gatta, Rizzi, and Marini based on modeling several low level mechanisms of the human visual system. The direct computation of ACE on an N × N image costs O(N4) operations. This article describes two fast approximations of ACE. First, the algorithm of Bertalmı́o, Caselles, Provenzi, and Rizzi uses a...

Polygon Clipping and Polygon Reconstruction

Polygon clipping is an important operation that computers execute all the time. An algorithm that clips a polygon is rather complex. Each edge of the polygon must be tested against each edge of the clipping window, usually a rectangle. As a result, new edges may be added, and existing edges may be discarded, retained, or divided. Multiple polygons may result from clipping a single polygon. Afte...
