− A Background Information Fusion (BIF) algorithm and its application in video target tracking is proposed in the paper. The BIF algorithm is based on the fact that there are redundant information between different frames. Unlike most of available tracking algorithms based on target features, which focus on the problems of what features the target have, and how does these features change when t...

Target tracking in a Wireless Sensor Network (WSN) environment is a challenging research problem. Interactive Multiple Model (IMM) is a popular scheme for accurate target tracking. The existing target tracking scheme used in WSN employs Kalman Filter (KF) which fails to track the target accurately due to non availability of target data at regular intervals and missing of packets. Though existin...

The efficient target tracking algorithm researches have become current research focus of intelligent robots. The main problems of target tracking process in mobile robot face environmental uncertainty. They are very difficult to estimate the target states, illumination change, target shape changes, complex backgrounds, and other factors and all affect the occlusion in tracking robustness. To fu...

A novel hybrid method for tracking multiple indistinguishable maneuvering targets using a wireless sensor network is introduced in this paper. The problem of tracking the location of targets is formulated as a Maximum Likelihood Estimation. We propose a hybrid optimization method, which consists of an iterative and a heuristic search method, for finding the location of targets simultaneously. T...

There are more and more bug reports in software. Software companies and developers invest a large number of resources into the dramatic accumulation of reports. We introduce Bayes classifier into bug reports compression, which is the first effort in the literature. For this purpose, the vector space model as well as some conventional text mining values, such as tf-idf and chi-squared test, are ...

Correlation tracking is used in civilian and military automatic target recognition and surveillance systems, to track objects based on their 2-dimensional shape. However traditional correlation-tracking systems have difficulty robustly detecting an object when the object is partially obscured by clutter. This paper describes one of the main problems of image-based correlation tracking systems, ...
