Image Auto-focus System Based on Remote Web Monitor

The algorithm based on digital image is widely used now. This paper puts forward a new auto-focus algorithm. The method adopts the smallest isotropy wavelet filter to get an image sequence of edge feature, then chooses the best-focused image with a criterion of energy target function, therefore fixes the accurate focus position. The remote monitor of auto-focus based on Web is carried out on an embedded system. Taking a microscope imaging system as a research object, the configuration of hardware platform and the development of software for an auto-focus system are finished
