Abstract
Systems and methods for segmentation of an image into tuned multi-scale regions that comprise similarity in the pixels contained in each respective region. A watershed transform sub-process is performed upon an edge strength map of the image. A process for deriving an edge strength map may comprise preprocessing the image, extracting channels from the image, applying an edge operator to each channel, enhancing edge signal, normalizing the edge channels, combining the edge channels, and enhancing the signal to noise ratio for the channel. Once the watershed transform is complete, decisions on which neighboring regions to agglomerate may occur based on the cost effectiveness of the mergers. As desired, the boundaries for the regions created are resolved.
