Image segmentation is a basic but important preprocessing to image recognition in computer vision applications. In this paper, we propose a pixel-based k-means (PKM) clustering to generate superpixels, which comprise many pixels with similar colors and neighbor positions. In contrast with conventional center-based clustering, the PKM method traces several nearer clustering centers for a pixel i...

Examining locomotion has improved our basic understanding of motor control and aided in treating motor impairment. Mice and rats are premier models of human disease and increasingly the model systems of choice for basic neuroscience. High frame rates (250 Hz) are needed to quantify the kinematics of these running rodents. Manual tracking, especially for multiple markers, becomes time-consuming ...

 ABSTRACTBackground: Although Electronic Portal imaging Devices (EPIDs) have originally developed for positioning verification, they can also be used for dosimetric purposes. In the current work, the dose response of minimum detectable thickness of a Scanning Liquid filled Ion Chamber EPID, SLIC-EPID, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was al...

During alloy solidification, many free grains in the melt have important effects on final microstructure and composition distributions. In this paper, grain motion is calculated based an interface tracking method coupled with a cellular automata (CA) method. First, capabilities of level set, simple linear calculation (SLIC), piecewise (PLIC) methods are compared, fidelity three models explored....

Unmanned surface vehicles (USVs) are receiving increasing attention in recent years from both academia and industry. To make a high-level autonomy for USVs, the environment situational awareness is key capability. However, due to richness of features marine environments, as well complexity influenced by sun glare sea fog, development reliable system remains challenging problem that requires fur...

The notion of singular limiting induced from continuum solutions (slic-solutions) is applied to the problem of cavitation in nonlinear elasticity, in order to re-assess an example of non-uniqueness of entropic weak solutions (with polyconvex energy) due to a forming cavity.

This paper presents a novel method to recognize current location of a mobile robot from input stereo images with visual and geometric features. We extract structural planes from 3D depth data by using SLIC (Simple Linear Iterative Clustering) based superpixel and RANSAC algorithm. The experimental results show that the proposed method using visual features and their geometric relationship provi...
