Abstract

This paper deals with the problems of point target detection and tracking initialization in infrared image sequence. A processing method based on median filter is adopted to process the original images and remove the correlated spatial noise. An accumulation scheme is implemented to suppress the temporal noise and improve the SNR. Because of the movement of target, it may form a point, a tiny blob or a trace on the accumulated image. The algorithm deals with all of these cases, a segmentation method based on the sum of the gray within the target region is proposed, because the sum is equal for all these cases statistically. Simultaneously the parameters of track initialization can be estimated through the trace of the target. Two infrared image sequence is used to testify this algorithm, the results of simulation indicate that this algorithm reaches a high performance.
