Figure 5From: Data cluster analysis-based classification of overlapping nuclei in Pap smear samples Visualisation of local minima points. Local minima points are marked with a white pixel (left handside images) and illustrated with intensity mesh in shades of blue (right handside images) for single and overlapped nuclei regions inside a previously defined boundary. a) There is only one local minima. b) Overlapping causes multiple intensity valleys inside the region.Back to article page
