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.

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

Improved moving target detection method

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
An improved optical flow method is proposed to trace moving target. Being different from other algorithms, the ill-posed problem is solved by designing the filters g and h and deriving the velocity field constraint equation. To confirm the performance of the algorithm, the improved optical flow method is compared with the correlation coefficient method

Improved Moving Target Detection Technology

Advanced Materials Research, 2014
In order to detect target clearly, a detection system based on DM642 was designed. The system used improved frame-difference method combined with the background subtraction to detect target. First, the CCD camera scanned the surroundings step by step, then the background model was built, and improved three-frame-difference method was used to get the ...

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 ...

Moving Targets Detection Based on Moving Saliency Calculation

International Journal of Signal Processing, Image Processing and Pattern Recognition, 2016
Moving targets saliency extraction is the key technology in moving target detection, tracking and recognition systems. In order to solve the problems for moving targets detection tasks, such as the background interference, target occlusion and so on, a new moving target detection method by moving saliency calculation is proposed. By the Quaternion Fast

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 ...

Hierarchical detection of moving targets on moving platforms

2009 IEEE Intelligent Vehicles Symposium, 2009
In the context of driving assistance, detection of moving targets is challenging when the automobile is witnessing very complex environment. The main challenges come from difficulties to tell foreground from moving background due to camera motion. We present an efficient method for target detection by hierarchically distinguishing the motion of targets
