| Abstract: | Based on the analysis of the property of target and background,an approach of point targets detection using wavelet transform algorithm of high frequency processing and wavelet correlation algorithm is presented. The technology of point target detection in infrared image sequences will be stressed when the target is far from the infrared image sensor. The experiment results have proved that the combination of wavelet correlation algorithm and part adaptive threshold can improve obviously the probability of the point target detection , and implement detection of point target who is far from the infrared image. |
