It adopts an information feedback and knowledge-based mechanism, brings forwardan image content retrieval algorithm based on layout feature extraction and multi-agent technology as the core of image content detecting-analysis system, and realizes automatic target classifier by fusion algorithm.

In allusion to the deficiency of image detecting ability of current network security system, anintelligent network security system model is developed based on image content detecting.

Influence of image content and cultural difference on white point setting;

An image content authentication system based on iris feature watermarking;

A survey of firewall technology based on image content filtering;

Based on an analysis of the serious influence of landslide seen at foreland along both banks of rivers in China in recent years on flood protection,navigation and ecological environment,the author discussed the important meaning,monitoring contents,instruments,data acquisition and analysis of dike safety monitoring.

Starting from assuring the safety monitoring of the construction of deep pit, the paper confirms the monitoring content and alarm correlation limit value and illustrates them by using an actual example.
