Stable tracking point extraction for infrared extended target based on contour smoothing and minimal inscribed circle

A New Palmprint Segmentation Method Based on an Inscribed Circle

Target Tracking Based on Virtual Grid in Wireless Sensor Networks

One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...

An Active Contour for Underwater Target Tracking and Navigation

This paper presents a vision based tracking system for routine underwater pipeline or cable inspection for autonomous underwater vehicles (AUV’s). The objective of this research paper is to investigate the issues of pipeline detection, including pose and orientation measurements in underwater environments. The proposed visual tracking system used an active contour method to track underwater obj...

Contour Extraction And Tracking Of Moving Vehicles For Traffic Monitoring

A robust algorithm is proposed in this paper for contour extraction and tracking of moving vehicles. A snake model is modified, in which directional information is utilized to guide the snaxels’ behavior. Then an adaptive shape restriction is applied to govern the scope of the snake’s motion, and Kalman filter is employed to estimate spatio-temporal relationship between successive frames. Moreo...

Ontological Smoothing for Relation Extraction with Minimal Supervision

Relation extraction, the process of converting natural language text into structured knowledge, is increasingly important. Most successful techniques use supervised machine learning to generate extractors from sentences that have been manually labeled with the relations’ arguments. Unfortunately, these methods require numerous training examples, which are expensive and time-consuming to produce...
