A locally statistical active contour model for SAR image segmentation can be solved by denoising algorithms

no code implementations10 Jan 2024 Guangming Liu, Quanying Sun, Jing Liang, Qi Liu

In this paper, we propose a novel locally statistical variational active contour model based on I-divergence-TV denoising model, which hybrides geodesic active contour (GAC) model with active contours without edges (ACWE) model, and can be used to segment images corrupted by multiplicative gamma noise.

Active contours driven by local and global intensity fitting energy with application to SAR image segmentation and its fast solvers

no code implementations19 Dec 2023 Guangming Liu, Qi Liu, Jing Liang, Quanying Sun

In this paper, we propose a novel variational active contour model based on Aubert-Aujol (AA) denoising model, which hybrides geodesic active contour (GAC) model with active contours without edges (ACWE) model and can be used to segment images corrupted by multiplicative gamma noise.

In this paper, we propose a novel variational active contour model based on I-divergence-TV model to segment Synthetic aperture radar (SAR) images with multiplicative gamma noise, which hybrides edge-based model with region-based model.
