加权三维Otsu方法在图像分割中的应用
Application of weighting 3D-Otsu method in image segmentation
摘要
Abstract
From the point of view of information divergence, this paper proposed a new weighting method of 3D-Otsu, which could obtain a precise segmentation result for inhomogeneous image. Since the three dimensions in 3D-Otsu method played different roles in segmentation of images, could obtain better results of segmentation by changing the weighting factors of the three dimensions in 3D-Otsu method. According to the characteristic of weighting method, the 3D-Otsu could be decomposed into three one-dimensions. So, this method could speed up the calculation and lower the computational complexity and made the weighting method more practical. With this method, this paper obtained an optimized segmentation result.关键词
