Based on chest images features, this paper presents a retrieval method with domination color of partition, gray level co-occurrence matrix and gradient image shape invariant moments, as well as the fusion of them and the technique of relevance feedback.

Therefore, an improved topologically adaptable snake (T-Snake) was presented, and then a method was given to segment lung parenchyma in chest CT image based on the improved T-Snake.

Auto-segmentation of cartilage and bone areas in thoracic vertebrae images;

With digital chest radiographs as research objects in this paper, several segmentation methods are presented to detect the ribs in digital chest radiographs, which include iterative probabilistic relaxation, K-means cluste.
