Balloon-like Active Contour Model Using Variable Closet Points

Left Ventricle Segmentation Using Active Contour Model

This study is based on the tracing of the left-ventricular endocardial borders of echocardiographic images. The algorithms used for border detection are the Active Contour Models (ACM) and also the one developed in the EchoPAC software. The mentioned algorithms were applied on apical two chamber view (A2C) in endsystole and end-diastole frames. The overlapping between borders detected using bot...

Building Segmentation using an Active Contour Model

This paper addresses the problem of building detection in high-resolution (1m) images and proposes an Active Contour Model as one of the solutions to ease the problem. In building segmentation, it is important to identify approximated building regions, i.e., the regions where buildings are likely to exist. Once the approximated building regions are identified, the problem of building extraction...

Protein Surface Modeling Using Active Contour Model

Sunspots and Coronal Bright Points Tracking using a Hybrid Algorithm of PSO and Active Contour Model

In the last decades there has been a steady increase of high-resolution data, from ground-based and spaceborne solar instruments, and also of solar data volume. These huge image archives require efficient automatic image processing software tools capable of detecting and tracking various features in the solar atmosphere. Results of application of such tools are essential for studies of solar ac...

Masses Characterization Using Active Contour

This paper presents the application of active contour or snake for the segmentation of masses on breast ultrasound images and the characterization of the segmented masses as malignant or benign. Initially, the balloon snake is chosen to segment the masses. Comparison on the masses areas segmented by the balloon snake is done against the areas traced by radiologist. Experimental result shows tha...
