In this study, a new active contour model based on local region information is proposed to segment colon tissue in CT image. Due to the large amount data of three-dimensional abdominal CT medical image and heterogeneous intensity regions, the traditional active contour models cannot get the ideal result. They usually have the sensitive limitations on the image noise and initialization. Therefore,...
This paper proposes an improved multilevel banded graph cuts method for colon segmentation. Accurate and quick colon extraction from 3D medical abdomen CT images is a crucial step in virtual colonoscopy. However, it is a challenge to extract colon tissues because of the local characteristics of colon tissues and multi-megapixel 3D medical images. Multilevel banded graph cuts method has drastically...
