Optical track initiator for multitarget tracking

Applied Optics, 1988
An optical processor for multitarget track initiation is presented. It uses the Hough transform to detect target tracks in a fixed time independent of the number of tracks present. In new results, we describe how the system produces target position and velocity estimates in linear time (with the number of targets). Tests of the system are presented for

Optical tracking novelty filter

Optics Letters, 1987
We demonstrate an optical filter that displays the time-dependent features of a scene. The heart of the device is an interferometer that is sensitive not to the difference between two optical paths lengths but to changes in the path-length difference. The interferometer arms share a phase-conjugating mirror. The phase conjugator ensures that, at steady

Cell tracking with optical imaging

European Radiology, 2008
Adaptability, sensitivity, resolution and non-invasiveness are the attributes that have contributed to the longstanding use of light as an investigational tool and form the basis of optical imaging (OI). OI, which encompasses numerous techniques and methods, is rapid (

Tracks storage in optical spark-chambers

Nuclear Instruments and Methods, 1972
Abstract A new technique in optical spark chamber pulsing is described, which allows tracks storage for a time of the order of 10 −3 sec. The mechanism producing this effect is discussed together with tests performed with different experimental conditions.

Intelligent Optical Tracking

2019 International Conference on Intelligent Computing and Remote Sensing (ICICRS), 2019
Optical Tracking System are very vital for target acquisition, surveillance and also in battle field. However, always it becomes challenging to realize the full potential of Optical Tracking System by overcoming the shortfall in the operator’s real-time decision apart from rough environment and unclear background.

Tracking through Optical Snow

2002
Optical snow is a natural type of image motion that results when the observer moves laterally relative to a cluttered 3D scene. An example is an observer moving past a bush or through a forest, or a stationary observer viewing falling snow. Optical snow motion is unlike standard motion models in computer vision, such as optical flow or layered motion ...
