Deep Active Contours for Real-time 6-DoF Object Tracking

IEEE International Conference on Computer Vision, 2023
This paper solves the problem of real-time 6-DoF object tracking from an RGB video. Prior optimization-based methods optimize the object pose by aligning the projected model to the image based on handcrafted features, which are prone to suboptimal ...

Region-edge-based active contours driven by hybrid and local fuzzy region-based energy for image segmentation

Information Sciences, 2021
This paper raises a region-edge-based active contour driven by the hybrid and local fuzzy region-based energy to segment images with high noise and intensity inhomogeneity. The energy functional consists of region energy and edge energy.

Learning Geodesic Active Contours for Embedding Object Global Information in Segmentation CNNs

IEEE Transactions on Medical Imaging, 2020
Most existing CNNs-based segmentation methods rely on local appearances learned on the regular image grid, without consideration of the object global information.

Multilure active contours

Proceedings of the 2005 ACM symposium on Applied computing, 2005
This paper presents a variation of the classic algorithm of active contours in order to improve the visualization of 3D reconstruction of anatomical structures in medicine. This 3D reconstructions are made from the obtained contours. This variation of active contour enables a better behavior of them.Other authors have already used snakes (active ...

Kernel active contour

2009 IEEE 12th International Conference on Computer Vision, 2009
Level sets and graph cuts are two state-of-the-art image segmentation methods in use today. The two methods are apparently different from each other not only because they originate from different theory foundations but also because they employ image information in different ways — level sets typically use image information in a point-wise way, whereas ...

Active contours driven by adaptive functions and fuzzy c-means energy for fast image segmentation

Signal Processing, 2019
The shortcoming of geometric active contours is that they are extremely sensitive to positions of initialization. Initial contours of the distance regularized level set evolution model must be set inside or outside target completely.

Automatic initialization of active contours and level set method in ultrasound images of breast abnormalities

Pattern Recognition, 2018
We propose a novel initialization method designed for active contours (AC) and the level set method (LSM), based on walking particles. The algorithm defines the seeds at converging and diverging configurations of the corresponding vector field. Next, the
