Live wire segmentation tool; Osteophytes


"Computer-assisted image segmentation can be a challenging problem. In previous research, manual segmentation was used for the detection of key features in cervical and lumbar x-ray images. In this research, a semi-automated live wire technique is investigated and is evaluated for the detection of anterior osteophytes in lumbar vertebrae. Convex hull-based features are extracted from manual and live wire segmented vertebrae for anterior osteophyte discrimination over 405 lumbar vertebrae, 204 abnormal vertebrae with anterior osteophytes and 201 normal vertebrae. A leave-one-out standard back propagation neural network was used for vertebrae classification. Experimental results show that manual segmentation yielded slightly better discrimination results than the live wire technique."--Abstract, page iii.
