Improved live-wire algorithm for interactive medical image segmentation

Lung extract is very important for computer-aided diagnosis,and it provides reliable diagnostic data for doctors.This paper presents an interactive lung segmentation method.Firstly,using optimized Gabor odd filter to filter chest X-ray image,and we can get a map of edge response energy.Then,using the edge response energy values to construct live-wire cost function,which can segment chest image.Test shows that this algorithm could correctly distinguish strong and weak edge,and extract the lung's contour quickly and effectively.Compared with the traditional algorithm,it reduces the number of human-computer interactions,which is more robust and efficient.
