摘要
提出了一种具有抗噪性能的二值图像边缘跟踪算法,并将其应用在掌纹识别中.实验表明:新算法与传统算法相比,能够快速准确地检测出二值图像的整个边缘,同时能够较好地去除图像中的噪声和毛刺.
An edge tracing algorithm based on binary image and its application on palm recognition is introduced. Compared with the traditional edge detection method using all kinds of differential operator, this algorithm can detect the edge rapidly and accurately. Simulation results on the palm recognition show that the edge tracing algorithm denoises and de-thorn well.
