Abstract:
1. A method comprising: receiving, by a computing device, an input image of an environment having a plurality of physical notes; separating, by the computing device, the input image into a plurality of channelized input images, each of the channelized input images associated with a different color; generating, by the computing device, a plurality of transformed channelized input images by applying edge detection to each of the plurality of channelized input images; processing, by the computing device, the plurality of transformed channelized input images to identify, based on edges detected within the transformed channelized input images, a plurality of polygons corresponding to the physical notes within the input image; grouping, by the computing device, the plurality of polygons from the plurality of transformed channelized input images into a plurality of groups, each of the groups comprising one or more of the polygons and corresponding to different one of the physical notes; and selecting, by the computing device, a representative one of the polygons from each of the plurality of groups for each respective physical note in the input image.
