A method for distinguishing a foreground object from a monochromatic background in a digital image depicting a foreground object in front of said monochromatic background. A outer edge intensity map is created of the foreground object to which a tracing process is conducted. A continuous edge map is created by utilizing the traced edges in the outer edge intensity map. By selecting a path on the continuous edge map based on average edge intensity, a final edge map is created. The pixels comprised within the final edge map are distinguished as the foreground object. Optionally, the final edge map may be refined utilizing certain techniques.

Systems and methods for segmenation by removal of monochromatic background with limitied intensity variations

Systems for segmenting an image based on perceptual information and methods for making and using same. According to one embodiment, input channels from an image are derived and analyzed by heuristic metrics to create categorical estimates. Examples of categorical estimates include a foreground channel estimate and a background channel estimate. Once created, the categorical estimates are merged to create a final channel estimate. The final channel estimate may represent the foreground or background of an image. Optionally, noise removal will also be conducted to improve the segmentation.
