【Abstract】 An algorithm for detecting and tracking the small infrared moving target was suggested. By utilizing the excellent quality of multi-wavelet, the infrared image was preprocessed with the proper pre-filter, and segmented by the Fisher algorithm and possible targets were segmented from the image. According to the moving characteristics of small infrared target, a method for extracting and tracking small moving target was adopted, using the neighboring region analysis and analyzing line fitting of moving target in the speed plane. The simulation experiments indicated that the whole algorithm was quite effective and especially suitable for the cases in which a target was partly occluded or missing occasionally.更多还原
