基于规一化割的声呐图像谱抠图分割
Sonar image spectral matting segmentation based on normalized cut
摘要
Abstract
When applying spectral graph theory to sonar image segmentation, the results are often not ideal. To solve the problem, a sonar image segmentation method combining normalized cut and spectral matting was presented. Firstly, morphological transformation was used for sonar image pretreatment to reduce the effect of a complex background. Secondly, digital matting techniques were introduced and the Laplace equation of the normalized cut algorithm was changed to obtain the image transparency estimation for segmentation. Finally, the sonar image segmentation results could be obtained by transparency processing. The simulation experiment shows the effectiveness of the proposed algorithm. Compared to the traditional spectral segmentation method, this algorithm does not segment the background of a sonar image, and can extract the target region accurately, obtaining better and more detailed sonar image object segmentation results. This improvement is also conducive to later identification.关键词
