NOTE RECOGNITION AND MANAGEMENT USING MULTI-COLOR CHANNEL NON-MARKER DETECTION

摘要

Techniques are described for creating and manipulating software notes representative of physical notes. A computing device comprises a processor and a note identification module executable on the processor and configured to separate an input image into a plurality of channelized input images. Each of the channelized input images are associated with a different color. The note identification module is configured to apply edge detection and feature extraction to identify polygons within each of the channelized input images and select, from the polygons from the channelized input images, a representative polygon for each of the physical notes in the input image.

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; and processing, by the computing device, the plurality of transformed channelized input images to identify, based on edges detected within the transformed channelized input images, polygons for respective physical notes in the input image, wherein each identified polygon is corresponding to a different one of the plurality of physical notes.
