This paper introduces a method of on-line handwritten Chinese character stroke recognition that is suited to the needs of character glyph analysis and the practical algorithm is given.

Measuring the shape and size of diamond grains by digital image identification method;

Image identification algorithm used in automatic inspection of surface cracks;

Design of Surverllance and Control Center Management Software in the Video Image Identification System;

Application of image recognition technology in fire detection system of ship;

Application of Image Recognition Technique to the Gear Quantity Examination;

Animal fiber diameter measuring algorithm using image recognition;

In the auto-detection system of the assembly holes of string piece based on machine vision,pattern recognition detection needs to obtaining shape and gray information of the image after image processed.

Synthetic discriminant function(SDF) are used instead for distortion invariant pattern recognition.

Grey-scale and fluorescent pictures of microalgae are taken in the same field of view and image processing techniques are adopted, such as threshold segmentation, contour and texture analysis, pattern recognition, and so on.
