Both 2-D contours extracted from MNIST digits dataset and MPEG-7 are reparametrized using the arc length parametrization. An illustration of this parametrization is given by the following image where ...

This application is originally used for 2D drone design. Users can create a curve contour, assign points as positions of rotors, and paint a given triangle mesh to assign color (weights) to each ...

Purpose The main objective of this study was to develop two-dimensional (2D) phase contrast (PC) methods to quantify the helicity and vorticity of blood flow in the aortic root.Methods This ...

A novel algorithm for human activity recognition is presented in this paper. This approach is based on a new 2D representation for the Histogram of Oriented Optical Flow (2DHOOF) describing the motion ...

Here, the diffusing molecules randomly bounce back (or scatter) from confining channel walls, which reduces their flow. “In channels with atomically-flat walls, however, such as those made from ...
