Most previous researches make an effort to embed hidden figures into another image and these methods are usually utilized for natural scenes but not for full structure pictures such as city maps. Therefore, the embedded results in the city maps potentially create unnatural virtual road networks or texture artifacts in both detailed features and shapes of city maps by ignoring the density control of map simplification or complication. In this paper, we propose a map-inspired reducing-and-increasing scheme to ameliorate these repulsive artifacts as well as enhance the shapes and detailed contents. The basic idea is to combine both reducing and increasing techniques, where the reducing approach removes non-significant roads and the increasing enhances local features to preserve the shape of salient objects, detailed features, and road network topologies. We show many map-inspired art images generated by our technique. We have tested the quality of the images in an extensive user study, showing better results than those by other state-of-the-art approaches.
