Figure 10From: A high-throughput screening system for barley/powdery mildew interactions based on automated analysis of light micrographsObject classification by linear discriminant analysis. The 55-dimensional feature space, in which both haustoria and other objects are described, is reduced to two dimensions. The linear discriminant analysis (LDA) projects the data onto axes of maximum discriminatory power. Both dimensions are highly correlated, so that considering multiple linear discriminant axes yields no benefit. Hence, the 1st axis is sufficient for classification.Back to article page
