Moving Targets Detection Based on Moving Saliency Calculation
نویسندگان
چکیده
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 Fourier Transform, the proposed method fuses four motion features as optical flows, direction vectors and frame difference. The moving saliency map, as the result, is generated. The experimental result demonstrates that our method has better ability to handle the problems in moving object detection, such as moving information loss in complex scene. The results with better accuracy score(Cgood=0.875 , Cfalse=0.028) are given by our method.

A parallel spatiotemporal saliency and discriminative online learning method for visual target tracking in aerial videos
Visual tracking in aerial videos is a challenging task in computer vision and remote sensing technologies due to appearance variation difficulties. Appearance variations are caused by camera and target motion, low resolution noisy images, scale changes, and pose variations. Various approaches have been proposed to deal with appearance variation difficulties in aerial videos, and amongst these m...
متن کاملOptimal Observer Path Planning For Bearings-Only Moving Targets Tracking Using Chebyshev Polynomials
In this paper, an optimization problem for the observer trajectory in the bearings-only surface moving target tracking (BOT) is studied. The BOT depends directly on the observability of the target's position in the target/observer geometry or the optimal observer maneuver. Therefore, the maximum lower band of the Fisher information matrix is opted as an independent criterion of the target estim...

In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...

متن کاملMoving Foreground Detection Based On Spatio-temporal Saliency
Detection of moving foreground in video is very important for many applications, such as visual surveillance, objectbased video coding, etc. When objects move with different speeds and under illumination changes, the robustness of moving object detection methods proposed so far is still not satisfactory. In this paper, we use the semantic information to adjust the pixel-wise learning rate adapt...
