摘要
从实用的角度分析了计算机辅助抗生素效价测量的方法 .采用基于灰度直方图的自适应图象分割方法对菌碟图象进行处理 ,并针对菌碟图象和图象分割算法的特点 ,提出了相应的图象预处理和目标筛选算法 ,以便能够快速有效地检测出抗生素形成的抑菌圈图象 ,最后根据生物检定的理论依据 ,计算出抗生素的效价 .
A computer automated system for measuring antibiotic potency is introduced in this paper. Based on the gray level histogram, an adaptive thresholding technique for image segmentation is used in the system. Furthermore, appropriate pre processing algorithms are adopted to improve the precision of segmentation, and filter rules are proposed to remove fake object. Finally, the antibiotic potency is calculated according to the biological assay theory.
