Abstract: To survey the localizing and tracking of aerial moving mulit-objects in complex background，the image segmentation methods of wavelet threshold de-noising method，mathematic morphology de-noising method and level set method are investigated，and a parallel fusion method of combination of two edge detection methods，the one is combination of wavelet with level set，the other is combing wavelet and mathematic morphology with level set，is proposed to detect the contour of moving objects.The experimental results show that parallel fusion combination method of wavelet，mathematic morphology and level set effectively extracts contour edging of objective and denoises background noise.

Key words: image segmentation, level set, wavelet transform, mathematic morphology, edge detection
