摘要:

针对水下高速射弹试验获取的超空泡图像中夹杂较多噪声,而传统边缘检测算法在自动边缘检测中抑制噪声效果差的问题。文中采用自适应多尺度小波边缘检测,对超空泡图像进行边缘检测。算法中首先对图像进行多尺度下的小波变换和相邻尺度间的梯度增强,再采用K均值聚类进行边缘的自动检测,得到不同尺度下的边缘,根据小波基的不同选择对应的多尺度融合方法进行多尺度融合,得到最终的边缘图像。实验表明,文中算法相比传统边缘检测算法,有效地抑制了图像中噪声,得到了更完整的边缘信息。

Abstract:

Aiming at the undesirable noise in the image of Super Vacuoles image,which is acquired from the high-speed projectiles test underwater,and the poor ability of traditional edge detection algorithm to restrain the noise in auto edge detection,this paper uses the self-adaptive multi-scale wavelet edge detection to detect the edge of Super Vacuoles image.First,we carry out the multi-scale wavelet transform and the enhancement of neighboring scale gradient.Then,we use the K-Means clustering to auto detection the edge,after which we obtain the edge of different scale.Finally,we choose the Multi-scale fusion strategy according to the wavelet and fuse the multi-scales edge into the final edge.The Experiments show that compared with the traditional edge detection algorithm,the proposed algorithm suppresses the edge noise more effectively,and obtains more information of the edge.

Key words: super vacuoles image;adaptive multi-scale wavelet edge detection algorithm;k-means clustering;multi-scale fusion
