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.

This paper proposes a new automatic detection method of motor commutating segment based on image recognizing technique,introduces the working principle and the frame of hardware of the system,and presents an image processing method that is suitable for this system.

In the process of detecting advertisement by computer, in order to overcome the problem of speech system, using the technology of image recognizing is the key.

By means of digital image processing techniques of color image composing,image fusion, principal component analysis with landsat-7 ETM+ image, combined with image recognizing and interpreting technologies based on geology knowledge, geological disasters along Motuo highway, debris flow, landslide, active fault, etc.
