Method for detecting microorganisms, device for detecting microorganisms and program

Abstract

用于检测微生物的方法,包括:训练步骤,用于由分类器基于培养基中的训练对象区域内的个别点上的颜色数据形成特征向量,将所述特征向量所规定的培养基内的点映射到高维特征空间,以及将因此获得的高维特征向量所规定的点集合ψ(x1)线性分离,从而按颜色归类出培养基类别(C1);和识别步骤,用于由分类器使用通过捕获在培养下的培养基的图像所获得的图像数据基于在所述培养基内的区域内的个别检查点上的颜色数据形成特征向量,将所述特征向量所规定的检查点(xj)映射到高维特征空间,以及判定因此获得的所述高维特征向量所规定的映射点ψ(x1)是否属于培养基类(C1),从而基于不属于培养基类(C1)的检查点识别菌落。
A method for detecting microorganisms, which comprises: a training step for forming, by a classifier, feature vectors based on color data on individual points within a subject area of training in a culture medium, mapping the points in the culture medium, that are specified by the feature vectors, on a high-dimensional feature space, and linearly separating the points ? (x1), that are specified by the high-dimensional feature vectors thus obtained, to thereby color-classify the class (C1) of the culture medium; and an identifying step for forming, by a classifier, feature vectors based on color data on individual inspection points within an area in the culture medium using image data obtained by capturing an image of the culture medium under cultivation, mapping the inspection points (xj), that are specified by the feature vectors, on a high-dimensional feature space, and determining whether or not the mapped points ? (xj), that are specified by the high-dimensional feature vectors thus obtained, belong to the class (C1) of the culture medium, thereby identifying a colony based on inspection points not belonging to the class (C1) of the culture medium.
