摘　　要：图像的边缘信息在图像的各种变换和处理中至关重要,边缘检测是为了获取更多的图像细节信息。根据边缘信息的多尺度特性和小波变换的性质,研究了基于B样条小波的图像边缘检测方法。采用三次B样条小波设计的平滑滤波窗算子,实现相对简单、效率较高。测试表明,该算子与其他边缘检测算子具有相似的视觉处理效果。The edge information of an image is of vital importance in various kinds of the image transformation and image processing, the detection of which is to gain more detailed information. The principle of B - spline wavelet was introduced based on the property of edge information and wavelet transform. The algorithm is relatively simple and efficient by adopting the cubic B -spline to design a smoothing filter. The result shows that this operator has similar visual effect to other edge detection algorithms.
