/**
 * Identify regions in a binary image likely to correspond to complete TMA cores,
 * based both on size and circularity.
 * @param bp - The binary image to process; 0 should be background, 255 foreground
 * @param minArea - Minimum area of a region to keep (in pixels)
 * @param maxArea - Maximum area of a region to keep (in pixels)
 * @param minCircularity - Minimum circularity of a region to keep.
 * @param labelCores - TRUE if the output should be a labelled image (unique integer value per core), otherwise a binary image will be returned
 * @param polyCentroids - A Polygon to which the centroids of the detected regions will be added (if not null).
 * @return Binary or labelled image showing containing only the regions of bp with shapes & sizes corresponding to likely complete TMA cores.
