abstract

object detection plays an important role in successfulness of a wide range ofapplications that involve images as input data. in this paper we have presented anew approach for background modeling by nonconsecutive frames differencing.direction and velocity of moving objects have been extracted in order to get anappropriate sequence of frames to perform frame subtraction. stationary parts ofbackground are extracted from differenced frames and joined as patches tocomplete the background model. there is also a special stage to handle changingregions of dynamic scenes. during the detection phase, the modeled background isupdated for every new frame. since it's not necessary to estimate each pixel grayvalue like the most common statistical methods, modeling process is not timeconsuming.different experiments show successful results even for challengingphenomena like environmental changes.

A Novel Method for Tracking Moving Objects using Block-Based Similarity

Extracting and tracking active objects are two major issues in surveillance and monitoring applications such as nuclear reactors, mine security, and traffic controllers. In this paper, a block-based similarity algorithm is proposed in order to detect and track objects in the successive frames. We define similarity and cost functions based on the features of the blocks, leading to less computati...

Tracking Moving Objects Using Adaptive Resolution

An algorithm is presented to visually track moving objects in a natural environment. Although various methods already exist to solve this task they usually fail to detect the precise motion of the target when the background gets more complex. They also require high computing power due to time consuming calculations of correlation-type motion detectors. The presented approach uses adaptive resol...

Tracking Moving Objects Improves Recognition

We describe a new family of algorithms that analyze time-varying scenes, recognizing and tracking learned objects over time. The new methods are intended to address key questions of moving images, including unpredictable moment-to-moment changes in location, size, orientation, lighting, and occlusion. We introduce a novel task in which objects revolve and rotate while suspended from a mobile’s ...
