A New Weak Edge Detecting Algorithm Based on BMO and Maximum Function

In this paper, a new algorithm to detect weak edges in medical images based on Bounded Mean Oscillation (BMO) and local maximum function has been presented. BMO functions are used to exact seed regions in an image. Local maximum function is used to grow up regions we are interested in. The algorithm has been tested by ideal geometric graphs and tested on different types of medical images. Testing results show that weak edges have been detected by the new algorithm successfully.
