Strategies for Tracking Tokens in a Cluttered Scene

چکیده

Tracking is an important approach to analyze long sequences of images in Computer Vision. Although it has extensively been studied in other domains such as in radar imagery, it was introduced only recently in Computer Vision, and is already recognized as an efficient approach to solving correspondence and motion problems. We describe in this paper some strategies for tracking with emphasis on practical importance. They include beam search for resolving multiple matches, support of existence for discarding false matches, and locking on reliable tokens and maximizing local rigidity for handling combinatorial explosion. We have implemented those strategies in a 3D line segment tracking algorithm and found them very useful.

Robust Object Tracking under Cluttered Environment

In this paper we recommend a novel method for detecting and tracking objects in the presence of cluttered background such as movements of leaves of trees, under various types of occlusion (object to object and object to scene occlusion) and scale change of object (small or large object) in real-time video. Object detection and tracking are two main terms of developing any tracking system. In ou...

Tracking in cluttered images

A new algorithm, the competitive attentional tracker (CAT) is proposed, which combines multiple velocity estimating filters to detect and track targets in cluttered images. Each filter tracks the motion of some scene content using a discrete grid representation for position and velocity beliefs. During operation, the filters can move between high confidence states (accurate tracking) and low co...

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...

M Tracker: A Multi-View Approach to Segmenting and Tracking People in a Cluttered Scene

When occlusion is minimal, a single camera is generally sufficient to detect and track objects. However, when the density of objects is high, the resulting occlusion and lack of visibility suggests the use of multiple cameras and collaboration between them so that an object is detected using information available from all the cameras in the scene. In this paper, we present a system that is capa...

Multi-camera Person Tracking in a Cluttered Interaction Environment

Tracking the head and hand in real-time are important tasks for developing an intuitive interaction system. We present a system for robust probabilistic tracking that integrates face detection, face and hand color tracking and foot tracking in a uniform way by using particle filters. The advantages of different cues like motion, color and face detection are combined to yield robust 2D and 3D po...
