Detection of Tongue Area using Active Contour Model

Active Contour Model Based Object Contour Detection Using Genetic Algorithm with Wavelet Based Image Preprocessing

In this paper, we present a novel, rapid approach for the detection of brain tumors and deformity boundaries in medical images using a genetic algorithm with wavelet based preprocessing. The contour detection problem is formulated as an optimization process that seeks the contour of the object in a manner of minimizing an energy function based on an active contour model. The brain tumor segment...

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

Rectal tumor boundary detection by unifying active contour model

The Project of 3D reconstruction of rectal wall structure aims at developing an analysis system to help surgeons cope with a large quantities of rectal ultrasound images, involving muscular layer detection, rectal tumor detection, and 3D reconstruction, etc. In the procedure of tumor detection, a traditional active contour model suffers some difficulties for finding the boundary of tumor when i...
