Abstract

According to the needs of dim and small target detection, a new detection algorithm based on wavelet transform and image fusion is put forward in the paper. In this algorithm, firstly, the original image is decomposed and reconstructed by wavelet and it is separated into a low frequency image and some high frequency images., secondly, the low frequency image is removed and the high frequency images are fused into a new image , finally, the fused image is segmented with threshold and the target is detected and signed. After the flight test validation, this algorithm has better accuracy and stability.
