Abstract: A remote video-on-demand digital monitoring system principally includes an image capture module, a server relay module and a video-on-demand module. The image data of said image capture module are stored in the server relay module through a telecommunication network. Through the telecommunication network, customers can browse the monitored web pages of the video-on-demand module via a browser, and view or store the monitored image data at a desired time segment according to a video-on-demand or movies-on-demand mode.

Abstract: An innovative method of automatic vehicle licence plate recognition is described, the vehicle licence plate recognition procedure is carried out respectively with reference to three component color red(R), green(G), and blue(B) grey level pixel maps, and then the results are reorganized. Sine the synthesized three component color R, G, B grey level pixel map is obtained by mixing R, G, B color component according to a definite proportion (for example dividing the sum of three component by 3), hence among the three component color grey level pixel maps, there must be at least one (R, or G, or B) whose contrast is better than that of the synthesized one. This most confidential one is picked out as the final result of the licence plate recognition.
