The lofty sense from the upward-viewing characteristic of Chinese contemporary memorial sculptures embodies the functions of memory,education and aesthetics;however,the multiple aesthetic tendencies and the spirit of equal exchange are the styles which Chinese contemporary memorial sculptures should have furthermore.

From the needs of practical struggle situation, belief features of God-worship are showing the clear tendency of utilitarianism and realism.

The relations among the natural attributes,visual characteristics,and processing technology of materials,new materials,or materials with new application forms were discussed.

By collecting samples of the network images, and inspecting their different visual characteristics, a content-based image classification system is raised.

In this thesis, firstly, video frame segmentation algorithm of multi-modal information based on artificial text and visual characteristics is proposed.

Analyzing 3D model visual features based on neural networks;

Face Recognition Based on Visual Feature Extraction and Kernel Discriminant Analysis;

Research on Visual Feature Based Image Retrieval Technology;

A method to reconstruct 3D solid using ObjectARX technology is presented, classifying and extracting every view features from engineering graphics, matching these view features, obtaining 3D primitives based on projection mode library, then using coordinate transform action and Boolean operations to create 3D solid, in the end a reconstruction system is developed in the AutoCAD environment.
