Original Abstract Submitted
Macros are placed on a canvas based on density map calculations. First, a grid representing the canvas is initialized. The grid is formed by grid cells. To place a macro on the grid, a coordinate on the grid is chosen, and multiple density maps are calculated using average-pooling filters of multiple resolutions or orientations. The lowest-level density map is described by the grid with each grid cell having a corresponding density value. The density value in a higher-level density map is calculated by performing an average-pooling operation on density values in a lower- level density map. The placement of the macro at the coordinate is validated when no density value in the density maps exceeds a corresponding density threshold.
