改进的三维Otsu图像分割快速算法
Improved fast three-dimensional Otsu image segmentation algorithm
摘要
Abstract
Aiming at the weakness of image detail and the huge calculation of the three-dimensional Otsu, an improved three-dimensional Otsu image segmentation algorithm is presented. A three-dimensional histogram based on gray level-average gray level-gradient is built. The original three-dimensional Otsu algorithm is decomposed into three one-dimensional Otsu algorithms. Based on the one-dimensional Otsu algorithm, a novel maximum scatter difference discriminant criterion is proposed. The criterion considers simultaneously both between-class distance and within-class distance. The experimental results show that the proposed algorithm does not only get satisfactory segmentation result, but also improves the calculation speed, which spends 900 times less than the recursive algorithm for the three-dimensional Otsu method.关键词
