Abstract: Method, device, computer program product, and apparatus for performing map classification is described. An unstructured map can be received to determine groups of components within the unstructured map having a same property. Shared properties within the unstructured map can include color, intensity, contrast, and line connectivity. A structured map can be generated by assigning each group of components detected within the unstructured map to a layer. A visual representation of the groups may be presented or displayed within a graphical user interface (GUI), such that each group is a selectable object for manipulation within the GUI. The GUI can receive selections or requests to update one or more properties of the group.

Abstract: A computer-implemented method for detecting a boundary of a building from an indoor map includes providing an electronic raster image of the indoor map. A floor plan included in the map is a first color and a background of the image is a second color. The method includes scanning the image a first time in a plurality of directions and coloring pixels of the image a third color as they are scanned the first time until a pixel is detected that is not the second color. Then the image is scanned a second time in at least two directions. The second scan includes marking a pixel a fourth color for each third color to non-third color and each non-third color to third color transition. The resultant pixels of the fourth color represent the boundary of the building.
