Tracking Across Multiple Cameras With Disjoint Views
Conventional tracking approaches assume proximity in space, time and appearance of objects in successive observations. However, observations of objects are often widely separated in time and space when viewed from multiple non-overlapping cameras. To address this problem, we present a novel approach for establishing object correspondence across non-overlapping cameras. Our multi-camera tracking...
متن کاملDisjoint Camera Track Matching by an Illumination Effects Reduction and Major Colour Spectrum Histograms Representation Algorithms
In this paper we present a disjoint camera track matching algorithm based on a “cumulative colour histogram transformation”, the “major colour” histograms matching and the post-matching integration algorithms. In order to reduce the “effects of variable illuminations” in disjoint camera environment, a cumulative colour histogram transformation is applied to located moving object image first. Th...
متن کاملHeight Measurement as a Session-based Biometric for People Matching Across Disjoint Camera Views
A surveillance session can be defined as the period between an individual’s entrance into a surveillance system, and their exit. Utilising this framework enables personal features, such as clothing and height estimates, to become invariant for the duration of the surveillance session. These can then be used as session-based biometrics for matching an individual uniquely as they move throughout ...
متن کاملModeling inter-camera space-time and appearance relationships for tracking across non-overlapping views
Tracking across cameras with non-overlapping views is a challenging problem. Firstly, the observations of an object are often widely separated in time and space when viewed from non-overlapping cameras. Secondly, the appearance of an object in one camera view might be very different from its appearance in another camera view due to the differences in illumination, pose and camera properties. To...
متن کاملEfficient illumination independent appearance-based face tracking
One of the major challenges that visual tracking algorithms face nowadays is being able to cope with changes in the appearance of the target during tracking. Linear subspace models have been extensively studied and are possibly the most popular way of modelling target appearance. We introduce a linear subspace representation in which the appearance of a face is represented by the addition of tw...
