利用空间填充曲线和灰度分布估计的声图分割

针对声图中的目标分割问题，提出了一种利用空间填充曲线和灰度分布估计的声图目标分割方法。该方法首先利用空间填充曲线将声图由二维矩阵变换为一维向量；其次在一维空间下进行滤波、灰度分布估计、阈值计算、分割处理；最后将分割后的一维向量逆变换为二维矩阵，得到目标分割结果。实际的声图处理验证了方法的有效性。

Research on sonar image segmentation by spatial filling curve and grayscale distribution estimation

Aiming at the problem of target segmentation in sonar images, a method based on space filling curve and grayscale distribution estimation is proposed and named as SFC-GDE Method. In this method, the space filling curve is firstly used to transform sonar image from two-dimension matrix to one-dimension vector, and then, the entire sonar image processing process, including filtering, grayscale distribution estimation, threshold calculation and image segmentation, are carried out in one dimensional space. Finally, the segmented one-dimensional vector is transformed into a two-dimensional matrix by inverse transformation to achieve target segmentation. Actual sonar image has been processed to verify the effectiveness of the proposed method.
