Abstract
An improved image segmentation algorithm is provided that identifies each object in an image. Pixels of the image are sorted based on a range of attribute values of the image. These pixels are then added to a labeling image one by one starting with an extreme point in the range of attribute values. Features are calculated for each object located and these features are matched with pre-defined acceptance criteria. If there is a match, the object is output to an output image. The steps of adding pixels to the image, evaluating the features of the resulting objects and outputting the objects are repeated until a stopping point is reached.
