Robust Evolution Method of Active Contour Models and Application in Segmentation of Image Sequence [PDF]
Journal of Electrical and Computer Engineering, 2018 Active contour models are widely used in image segmentation. In order to obtain ideal object boundary, researchers utilize various information to define new models for image segmentation. However, the models could not meet all scenes of image.

A Novel Adaptive Fractional Differential Active Contour Image Segmentation Method
Fractal and Fractional, 2022 When the image is affected by strong noise and uneven intensity, the traditional active contour models often cannot obtain accurate results. In this paper, a novel adaptive fractional differential active contour image segmentation method is proposed to ...

A Model Based Dual Active Contour [PDF]
Procedings of the British Machine Vision Conference 1994, 1994 Active contours are now established as a technique for extracting salient contours from an image. Unfortunately the original technique suffers from many problems. A novel model-based dual active contour, a method of integrating global shape information with two active contours, has been developed to overcome the primary problems; sensitivity to ...

Image Segmentation Algorithm Combining Visual Salient Regions and Active Contour [PDF]
Jisuanji kexue yu tansuo, 2022 When the traditional regional active contour model is used to segment the weak edge image, the evolution curve is subject to background interference, and it is easy to fall into the local extreme value, which leads to slow evolution speed.
