Abstract
Methods, apparatus, and other embodiments detect nuclei in histopathological images. One example method includes accessing a histopathology image that includes a plurality of pixels, generating a gradient field map based on the histopathology image, generating a refined gradient field map based on the gradient field map, calculating a voting map for a member of the plurality of pixels based, at least in part, on the refined gradient field map and a voting kernel, generating an aggregated voting map based on the voting map, computing a global threshold, and identifying a nuclear centroid based on the global threshold and the aggregated voting map.
