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

摘要: 针对复杂背景和多目标空中运动物体的定位和跟踪问题,研究了基于小波变换阈值去噪方法、数学形态学去噪方法与水平集方法结合的图像分割方法,提出了基于小波变换阈值去噪与水平集结合方法以及基于小波变换阈值去噪、数学形态学去噪与水平集结合方法的并行融合图像分割方法,对运动目标进行边缘检测。实验结果说明,基于小波变换、数学形态学与水平集方法结合的并行融合图像分割方法能够有效地提取目标物体的轮廓,抑制背景噪声。
