• Compared to ground-based observation, space-based observation is an effective approach to catalog and monitor increasing space targets. In this paper space target detection in video satellite image with star image background is studied. An adaptive space target detector based on prior information is proposed. Firstly, bilateral filter is used to decrease noise. Then a single frame image is segmented using adaptive thresholding. Considering the continuity of target motion and brightness change, adaptive thresholding is based on local image properties and prior information of previous frames detection and Kalman filter. Then the algorithm uses the correlation of target motion in multi-frame to detect the target from stars. Experimental results with video image from Tiantuo-2 satellite show that this algorithm provides a good way for space target detection.
