Detection of moving targets with a moving camera

2009 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2009
In this paper we propose a new method of detecting moving objects from a moving camera based on SIFT(The Scale Invariant Feature Transform) features matching and dynamic background modeling. Firstly, feature points are extracted by SIFT algorithm to compute the affine transformation parameters of camera motion, and guided by RANSAC to remove the ...

Detection and identification of moving targets

Vision Research, 1983
Abstract Though they could distinguish a moving target from a blank field, subjects in earlier work often greatly misperceived the direction of the movement. This observation was followed up in three experiments comparing detection of moving random-dot patterns to identification of the patterns direction of movement.

Invariance in moving target detection

IEEE Transactions on Information Theory, 1985
Some schemes for detecting moving point targets against structured backgrounds from observations on the input of an imaging system are investigated. When the velocity of the target and the background image are considered as known, it is shown that the uniformly most powerful detector, invariant with respect to image intensity variations, consists of ...

On-the-move independently moving target detection

SPIE Proceedings, 2007
This paper describes a system for automatically detecting potential targets (that pop-up or move into view) and to cue the operator to potential threats. Detection of independently moving targets from a moving ground vehicle is challenging due to the strong parallax effects caused by the camera motion close to the 3D structure in the environment. We
