The gray image of nature objects surrounding us satisfies the fractional Brownian motion (fBm) model. In this paper, the limitations and disadvantages of available methods based on fBm model are pointed out and a novel edge detection method based on fractal theory is proposed. Moreover, an edge evaluation method is introduced to analyze its performance. The(More)
The leaky magnetic flux detecting equipment is based on the theory of electric-magnetic detection. It has many advantages in detecting working pipeline such as high detecting speed, long detecting line, little undetected area, and so on. The equipment can't be directly controlled by outside while it's running, so detecting signals must be stored in real(More)
