This paper focuses on the algorithm theory of the two-dimensional wavelet transform which is used for image edge detection. To simplify the algorithm, the author propounds to turn the two-dimensional dyadic wavelet to onedimensional dyadic wavelet that can be divided into product. We can use the filter to achieve the wavelet multiplescale edge detection quickly. Simultaneously, the process that the wavelet transform used for the multiple-scale edge detection is discussed in detail. Finally, the
