This paper presents a new exemplar-based framework for completing video with large space-time holes,considering video completion as a process of global optimization on a 3D graph embedded in the space-time video volume.

Based on research of image completion,a video inpainting method with improved texture synthesis is proposed.

Digital image and video inpainting mainly aims at filling in missing pixels in an unknown region of an image or video in a visually plausible way.

The application of long-distance digital video supervisory and control technique in building construction project;

New method of signal design of digital video;

An improved collusion-secure digital ringerprinting scheme for digital video;

Talk bout digital video frequency monitor and control weighing system;

Study on digital video frequency long-distance supervisory control system of substation based on network communication;

Then,based on digital video frequency,image compression,wireless communication and long-distance control technologies,a project of WLAN is designed and exploited.

It is completed a system in the painting objects on a platform in the repair quickly and easily repair inquiries about the paintings framed knowledge and achieved our purpose of better doing the digital repair works.
