针对一维最大类间方差算法(1-Otsu)抗噪性能较低、二维最大类间方差算法(2-Otsu)计算复杂度高、实时性差的问题,提出一种基于改进的萤火虫算法(FA)优化二维Otsu图像分割算法(FA-2-Otsu)。
English Description：
Aiming at the problems of low anti noise performance of one-dimensional maximum interclass variance algorithm (1-otsu) and high computational complexity and poor real-time performance of two-dimensional maximum interclass variance algorithm (2-otsu), a two-dimensional Otsu image segmentation algorithm (fa-2-otsu) optimized based on improved firefly algorithm (FA) is proposed
