最大类间方差( Otsu)图像分割法是常用的一种基于统计原理的图像阈值分割方法。为了改善Otsu耗时较多、分割的精度低、易产生图像误分割等不足,将猴王遗传算法与Otsu算法结合,运用猴王遗传算法的原理,寻找图像灰度的最大类间方差,即最佳阈值。结果表明,结合后的方法不仅提高了图像的分割质量、缩短了运算时间,而且非常适合图像的实时处理。
最大類間方差( Otsu)圖像分割法是常用的一種基于統計原理的圖像閾值分割方法。為瞭改善Otsu耗時較多、分割的精度低、易產生圖像誤分割等不足,將猴王遺傳算法與Otsu算法結閤,運用猴王遺傳算法的原理,尋找圖像灰度的最大類間方差,即最佳閾值。結果錶明,結閤後的方法不僅提高瞭圖像的分割質量、縮短瞭運算時間,而且非常適閤圖像的實時處理。

Maximum between-class variance ( Otsu ) image segmentation method is a common image threshold segmentation method based on statistical theory , but Otsu image segmentation method has some disadvantages , such as more time-consuming , low segmentation accuracy and false image segmentation .Combining the principles of monkey king genetic algorithms, with Otsu algorithm, image gray, just as optimal threshold, was found.The results show that combined method not only improves the quality of image segmentation but also reduce the computation time .It is very suitable for real-time image processing .
