Methods and apparatuses 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 ranking a plurality of regions of a raster image in a scoring matrix based on color similarities between each of the plurality of regions; and automatically merging certain ones of the plurality of regions connected through at least one of an edge and a vertex based on the scoring matrix. In addition, the method may include merging other regions of the plurality of regions without considering the scoring matrix when the other regions are smaller than a threshold number of pixels and automatically removing artifacts and noise from the raster image based on the threshold number of pixels.
