Based on the fourier transform and the wavelet transformation of the digital image processing

Along with the development of information technology, digital signal filled with the whole world, we see the image can be converted to be computer to deal with a digital signal. Digital image processing is through computer tool, with digital image signal by a series of processing operations, and get people with the needs of the application. This paper introduces the Fourier transform and wavelet transform algorithm and its application. These include, spatial analysis, frequency domain analysis, linear transformation and digital image processing basic point operations, filtering, enhance, etc. The advantages of wavelet transform with the traditional Fourier transform supplement each other on image information processing more ideal.
