Application of Singular Value Decomposition in Pest Image Detection System

The automatic detection system of pest in stored grian is always discussed. Usually this kind of system is based on image processing. The CCD camera is used to get the pest image, and then transmit to computer. There are several problems in this procedure. The obtained image is usually a degradation image, and after transmitting to computer, the image must be stored in hard disk as historical data. The space is occupied. In order to solve the problems, the image restoration, enhancement, and compression should be done. In this paper, singular value decomposition is applied to realize the restoration, enhancement, and compression. The experiments using Matlab 7.0 demonstrate that this method is effective and useful in pest image detection system.
