Several key techniques on image processing are studied,including binarization,thinning and filtering. A new denoising method is proposed. This method uses weighting median filtering first,then uses wavelet analysis. At the same time, the weight is improved through using genetic algorithm. The calculative work of wavelet analysis is always very large, a relative simple method is provided, so that calculation can be done on PC computer.
