摘要：
This paper presents a lifting wavelet based edge detection algorithm for NaXi Pictographs, effectively reducing noises while improving the precision, which makes up the drawbacks of traditional edge detection. It is proved by emulation that compared with Laplace operator, Sobel operator, Canny operator, and multi-scale wavelet edge detection algorithm, this algorithm has better detection effect.
