considered and if all neighbors have sufficient coverage then that fact is stored the right distance later if the corresponding pixel has enough coverage to be a reload exhibiting destination only considering pixels with corresponding reload causing sources then its neighborhood is considered here a check that all of the neighborhood has sufficient coverage is made and that its edge content is low at this point it is tentatively reload causing the next step is to look at any tentatively reload causing pixel and check its neighborhood if they are tentatively reload causing as well the method is done a reload causing pixel has been found the portion where neighboring pixels are checked to see whether they are tentatively reload causing could be done by building a boolean map of results where a location in the map is true if the corresponding pixel is reload causing and then forming the logical and of all locations in a neighborhood thereby combining the neighboring results other implementations are possible the exemplary method uses a reduced resolution image where the resolution is selected so that the minimum feature width corresponds to approximately three pixels wide in an alternative embodiment the image might use a higher resolution image including a full resolution image in which case the neighborhoods used.
