| 摘 要： | 针对枪口烟雾图像的不规则性以及烟雾扩散速度快等特点,传统的边缘检测算法无法高效地提取烟雾边缘轮廓的问题,对烟雾图像采集技术、烟雾图像预处理技术以及烟雾图像边缘检测技术进行了研究,提出了一种改进的二进小波和抗噪形态学融合的边缘检测算法.首先,在 B 样条二进小波基础上,将二进小波消失矩的阶数提高到四阶;其次,选取方向不同的结构元素,得出改进的形态学算子;最后,用小波逆变换重新构造枪口烟雾图像,对其进行锐化处理,输出边缘信息.仿真结果表明,该算法检测出来的枪口烟雾图像边缘定位准确且清晰完整,能有效抑制噪声,在客观方面优于传统的边缘检测算法.

| Abstract: | In view of the irregularity of muzzle smoke image and the fast speed of smoke diffusion , the traditional edge detection algorithm can not extract the smoke edge contour efficiently．This paper studies the smoke image acquisition technology , smoke image preprocessing technology and smoke image edge detection technology , An improved edge detectiona lgorithm based on the fusion of dyadic wavelet and anti noise morphology is proposed．Firstly , based on B-spline dyadic wavelet , the order of dyadic wavelet vanishing moment is increased to quartic ; Secondly , the improved morphological operator is obtained by selecting structural elements with different directions ; Finally , the muzzle smoke image is reconstructed by inverse wavelet transform , and the edge information is output by sharpening．The simulation results show that the edge of muzzle smoke image detected by the algorithm is accurate and clear , which can effectively suppress the noise , and is better than the traditional edge detection algorithm in the objective aspect． |
