The discussion and simulation for image edge detection techniques based on wavelet transform algorithm


Based on the characteristics of wavelet analysis, this paper designs the algorithm on the four steps of the image edge detection filtering, enhancement, detection and localization, getsthe threshold with the best effect is 0.009, uses Matlab simulation, compares its simulation results with the classical simulation results, obtains that wavelet transform algorithm avoids the appearance of noise and false edge in image edge detection, andreflects the advantages of the algorithm in the application of this field.
