A proposed Algorithm for Interactive Geometric Shapes Recognition [PDF]

Engineering and Technology Journal, 2014
A geometric shapes recognition algorithm is proposed in this paper. This algorithm is interactive which means that if not all the desired shapes are recognized then the recognition process is repeated by the user to improve the capability of the process.

Introduction of Lazy Luna an automatic software-driven multilevel comparison of ventricular function quantification in cardiovascular magnetic resonance imaging

Scientific Reports, 2022
Cardiovascular magnetic resonance imaging is the gold standard for cardiac function assessment. Quantification of clinical results (CR) requires precise segmentation. Clinicians statistically compare CRs to ensure reproducibility.

Geometric Constraint Programming (GCP) Implemented Through GeoGebra to Study/Design Planar Linkages

Machines
In the study and design of planar mechanisms, graphical techniques for solving kinematic analysis/synthesis and kinetostatics problems have regained interest due to the availability of advanced drawing tools (e.g., CAD software). These techniques offer a

Surveying Reality (SurReal): Software to Simulate Surveying in Virtual Reality

ISPRS International Journal of Geo-Information, 2021
Experiential learning through outdoor labs is an integral component of surveying education. Cancelled labs as a result of weather, the inability to visit a wide variety of terrain location, recent distance education requirements create significant ...

svMorph: Interactive geometry-editing tools for virtual patient-specific vascular anatomies [PDF]

Journal of Biomechanical Engineering, 2022
We propose svMorph, a framework for interactive virtual sculpting of patient-specific vascular anatomic models. Our framework includes three tools for the creation of tortuosity, aneurysms, and stenoses in tubular vascular geometries.

The Frame Game

Journal of Mathematics Education at Teachers College, 2011
In this article, the authors explore framing, a non-multiplicative technique commonly employed by students as they construct similar shapes. When students frame, they add (or subtract) a “border” of fixed width about a geometric object.
