Parallel Marker Based Watershed
Abstract. The parallel watershed transformation used in grayscale image segmentation
is here augmented to perform with the aid of a priori supplied image cues, called markers.
The reason for introducing markers is to calibrate a resilient algorithm to oversegmenta­
tion. In a hybrid fashion, pixels are first clustered based on spatial proximity and graylevel
