中文摘要: 出芽率是反映酵母菌生长的重要质量标准之一,目前对于酵母菌的出芽率的统计分析主要通过技术人员人工显微镜观察和统计,准确性和效率受到影响,不能适应工业生产的需求。提出一种基于凹点检测的椭圆拟合方法,根据酵母菌通常近似椭圆的特点,通过对酵母菌进行凹点检测之后再进行椭圆拟合的方法,分别统计出图像中酵母菌总数和出芽菌体数,进而判断出酵母菌的出芽率。实验表明,该方法可以准确有效地检测出酵母菌的出芽率。
Abstract:The budding rate was one of the standard to reflect the growth of yeast, but currently the analysis of the yeast growth were mainly through technical and statistical manual microscopy, cannot meet the needs of industrial production for accuracy and efficiency are affected. This paper presented a approach of ellipse fitting method based on concave points detection, according the characteristic that Yeast was usually approximate ellipsoid, by fitted ellipse after found concave points, counted the total number and the budding number of the yeast in the image respectively, then determined the rate of budding yeast. Experimental results show that the approach can detect budding yeast detection rate accurately and effectively.
