ABSTRACT:
Methods and systems to merge and/or remove (e.g., edges, regions, vertices, etc.) in a planar map of a raster image are disclosed. In one embodiment, a method includes identifying color similarities between each of a plurality of regions of an image and merging neighboring regions based on the color similarities. In addition, the method may include determining a merging order and merging certain regions based on the merging order; merging other regions without considering the merging order when the other regions are smaller than a threshold size; and removing artifacts and noise from the image based on the threshold size.
