The Adapteva Epiphany MIMD architecture is a scalable, two-dimensional (2D) array of RISC cores with minimal uncore functionality connected with a fast 2D mesh network on a chip (NoC). We apply a threaded MPI programming model for image processing kernels including a 2D Fast Fourier Transform (FFT) with high-pass filter for edge detection; local operators for Gaussian image smoothing; and a Sob...

This research employs a nondestructive, rapid, high accuracy and full-field material characterization platform which integrates quantitative laser ultrasound visualization system (QLUVS) with mechanical property mapping reconstruction algorithm. The QLUVS uses a pulsed laser generate acoustic waves with fast scanning mechanical to research two dimensional scanning goal and then detected with a ...

In this paper, we describe a new mechanism of cellular selection as an improved Genetic Algorithm for some optimization problems like Cellular Channel assignment, which have multi feasible/optimum solution per one case. Considering the problems and the nature of relationship among individuals in population, we use 2-dimension Cellular Automata in order to place the individuals onto its cells to...

PURPOSE To retrospectively evaluate the technical quality of and the visibility of the biliary tree and pancreatic duct on magnetic resonance (MR) cholangiopancreatographic (MRCP) images obtained with a single-breath-hold three-dimensional (3D) fast-recovery fast spin-echo (FRFSE) sequence in comparison with conventional two-dimensional (2D) single-shot fast spin-echo (SSFSE) thin-section and t...

In this paper a new approach for classification is presented, the “Fast Projection Plane Classfier”, abbreviated here to FPPC. The main idea of FPPC is very simple: A classification problem for n-dimensional feature vectors is transformed into several 2 dimensional (2d) classification problems. Each transformation is a projection of the feature space into a plane. The projection into 2d-planes ...

Terrains can be rendered efficiently with rectangular 2D grid of heights. Terrain on spheres, on the other hand, can be rendered using Hierarchical Triangular Mesh (HTM) but the representation does not fit directly with 2D grid of heights. We present a unified representation of HTM and clipmapping using Hexagonal Geometry Clipmaps. This provides one to one correspondence of vertices and heights...
