一种改进的一维Otsu快速算法
An improved one-dimensional Otsu fast algorithm
摘要
Abstract
Threshold segmentation is one of the most commonly used image segmentation methods,and the solution of threshold is also the focus of image processing. The traditional Otsu algorithm is an exhaustive threshold solution method,which needs to traverse each gray value,calculate the interclass variance taking the gray value as the threshold value,and make a large number of unnecessary calculations. As a result,the traditional Otsu algorithm may not be appropriate to be applied in some environments with high real-time performance requirements. Therefore,an improved fast Otsu algorithm is proposed. The hunting scope of the traversed gray was reduced after importing the image complexity and its related properties. A fast calcula-tion method is used in the scope of the traversed gray,which executes secondary acceleration in comparison with the traditional Otsu algorithm.The experimental results show that this algorithm improves the calculation speed in comparison with the traditional Otsu algorithm,and the image segmentation results of the two algorithms are the same.关键词
