Abstract :
The selection of wavelet scale and filter coefficients is a key technology for wavelet edge detection. In this paper, we propose an algorithm of constructing adaptive spline wavelet filter coefficients based on the genetic algorithm. We detect image edges by employing the obtained filter coefficients, and obtain a good effect of edge extraction by integrating the edge connection algorithm. Finally, experimental results are compared with Canny´s operator, and demonstrate the performance of our algorithm
