Fig. 6

Examples of detected glomeruli. The estimated boundaries of the glomeruli are depicted with red rings. The areas surrounded with blue rings are passed through the pre-screening stage, but removed in the classification stage. The numbers are the SVM scores resulting from the classification stage. The areas with SVM scores more than θ=−1.5 are classified as a glomerulus. It can be observed that false positives such as vessels detected in the pre-screening stage were successfully removed in the classification stage
