Abstract :
Diagnosis and monitoring of kidney diseases and transplants is supported by microscopic analysis of needle-core biopsy samples. The current methods of analysis are affected by inconsistencies, bias, and inaccuracies. We propose and evaluate image processing methods for automatic segmentation of cell nuclei in digital images of renal biopsy samples. The methods evaluated include automatic thresholding, adaptive thresholding, and morphological granulometry. The results are compared to annotations made by an expert pathologist of more than 1500 cells in 18 images from different patients. The three methods provided true-positive ratios in the range 0.80 to 0.93.
