investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Geometric Active Contour Model for Highway Extraction

In this paper, a new framework for semi-automatic feature extraction is developed and applied to highway extraction and vehicle detection from multiple-frame aerial photographs. The basis of the new framework is a geometric deformable model. This model refers to the minimization of an objective function that connects the optimization problem with the propagation of regular curves. The implement...

vesselness‑guided active contour: a coronary vessel extraction method

vessel extraction is a critical task in clinical practice. in this paper, we propose a new approach for vessel extraction using an active contour model by defining a novel vesselness‑based term, based on accurate analysis of the vessel structure in the image. to achieve the novel term, a simple and fast directional filter bank is proposed, which does not employ down sampling and resampling used...

An Automatic Wheel Contour Extraction Method

Wheel contour extraction from image is an important unit of any vision-based traffic accident analysis system, and automatically doing it is still a difficult task due to various distracting factors such as low contrast between the wheel and the ground, different wheel types and various weather conditions etc. In this work, a new automatic wheel extraction method is proposed, in which rather th...

Radial-searching contour extraction method based on a modified active contour model for mammographic masses.

In this study, we developed an automatic extraction scheme for the precise recognition of the contours of masses on digital mammograms in order to improve a computer-aided diagnosis (CAD) system. We propose a radial-searching contour extraction method based on a modified active contour model (ACM). In this technique, after determining the central point of a mass by searching for the direction o...
