Note recognition and management using color classification

摘要

This disclosure describes techniques for creating and manipulating software notes representative of physical notes. For example, techniques are described for recognizing physical notes present within a physical environment, capturing information therefrom and creating corresponding digital representations of the physical notes, referred to herein as digital notes or software-based notes. At least some aspects of the present disclosure feature system and methods for note recognition using color classification. The system receives a visual representation of a scene having one or more notes, where each note has a color. The system generates indicators indicative of color classes of pixels in the visual representation. The system further determines a general boundary of one of the notes based on the indicators.

主权项

1. A method of extracting note content using a computer system having one or more processors and memories, comprising:
receiving image data containing a visual representation of a scene having a plurality of notes, each of the plurality of notes having a color; generating, by the one or more processors, a plurality of indicators, each indicator indicative of a color class of a respective pixel or group of pixels in the image data and based on color values of the pixel or group of pixels; based on the plurality of indicators, determining, by the one or more processors, a general boundary within the image data of one of the plurality of notes; and extracting, by the one or more processors and from the image data, content of the one of the plurality of notes using the general boundary.
