A detection algorithm for the small moving target in infrared image sequences with the dynamic background

An algorithm to detect the small moving target in infrared image sequences with the dynamic background is proposed in this paper. Based on the registration of four continuous frame images, the image sequences are processed by the 1D wavelet transform to separate the target from background. And then the images that contain the moving target information are multiplied by pixel so as to obtain the target enhanced images and extract the moving small target after segmentation. Results of this experiment indicate that the proposed algorithm can detect and locate both slow and fast small moving targets effectively.
