Robust Event Detection and Retrieval in Surveillance Video
… background modeling and foreground detection; a connected component labeling algorithm is then employed to label the foreground pixels. A Kalman filter approach is used to build models for the entities of interest (people and bags), which is combined with color histograms for tracking. We use …

Characterizing the Movement of Contaminant Liquid Metal Particles when subject to Electric Pulses, within the Context of Z-pinch Fusion Reactors
… automated particle tracking algorithms with connected-component labeling and two-point correlation functions to monitor ejecta trajectories. Results reveal an average ejected particle velocity of 2.54 m/s (±3.58 m/s), with particle formation likelihood peaking at velocities around 1.14 m/s. …

Generic FPGA Preprocessing for Astrophysics Instruments in HLS
… so, we also present a novel HLS-based two-pass connected-component labeling (CCL) implementation that can be easily switched between 4-way and 8-way CCL.</p>

Detection and Recognition of U.S. Speed Signs from Grayscale Images for Intelligent Vehicles
… in the input image. We have utilized the idea of connected component labeling technique and adapted it for the grayscale images, to divide the input image into a set of regions. The recognition phase calculates the invariant features of the inner parts of the detected regions using Hu’s moments. …

Automating Pre-Stack Migration Enhancement and Image Quality Analysis
… of segregating a reflection is called the connected-component labeling (CCL) method and is the leading technique to extract any feature that has a continuous form within the ADCIGs. Moreover, this method is insensitive to scattered noise so that it is a suitable approach to classify what is …

Numerical simulation and modeling of two-phase flows using the volume-of-fluid method
Two-phase flows are of great interest in natural and industrial applications such as cavitation, spray atomization, and bubbly flows. As a two-phase system grows in complexity, analytical approximations of fluid behavior and experimental observations become more challenging. To make the detailed …

A Simple Machine Vision System for Improving the Edging and Trimming Operations Performed in Hardwood Sawmills
… extraction, both global and local segmentation, connected component labeling and small area elimination and merging. Processing results obtained of green red oak samples show that both hardware and software of the prototype system seem to work well. However, since the program needed to actually …
