Fig. 6From: Large-scale localization of touching somas from 3D images using density-peak clusteringLocalization of somas from large-scale dataset. a The max-intensity projection of an mouse hippocampal image stack with a volume of 4.3 × 2.7 × 2.4 mm3 and the detected soma centers (white dots). Sub-figures A and B indicate the localizations of densely positioned somas and sparsely positioned somas. b The localization and segmentation of touching somas in three connected components. Note that different gray level here represents different somas. c-e The frequency histograms of radius, overlap-measure and average gray value of detected somas. (radius: average distance between perimeter points of a soma and its center; overlap-measure, for a soma pair that consists of a soma and its closest soma, let s and d denote the sum of radius of these two somas and the distance between the two soma’s centers, overlap-measure is defined as the ratio of s to d; average gray value: average gray value of all points in a soma.)Back to article page
