To solve the problem of automatic classification for ultrasound placenta images,we put forward an algorithm based on adaptive multiple neural networks.

The methods for determining the fiber volume fraction in carbon fabric reinforced composite laminates were developed by using the processing and analyzing techniques of section images of laminates, which are sampled by the use of CCD camera and A/D device.

There are sometimes shadows,such as cars、trees and buildings,on road surface images,which make it difficult to abstract and recognize the features.
