A method for digitizing sticky-back paper notes, comprising: receiving, by a computing device, an input image of an environment having a plurality of overlapping sticky-back paper notes, wherein each of the plurality of sticky-back paper notes comprises a body having a background color and a border around the body having a border color different from the background color, and wherein the input image comprises one or more physical grouping indicators indicating a physical grouping of the plurality of sticky-back paper notes; processing the input image with the computing device to apply a color segmenting process to identify, based on the background color and the border color of each of the overlapping sticky-back paper notes, boundaries for each of the overlapping sticky-back paper notes in the input image; processing the identified borders of each of the overlapping sticky-back paper notes to extract content for each of the respective overlapping sticky-back paper notes, wherein the extracted content for a respective sticky-back paper note includes at least a portion of the body and portions of the border of the respective sticky-back paper note; generating, by the computing device, a plurality of digital notes, each of the digital notes corresponding to one of the identified overlapping sticky-back paper notes; associating, by the computing device, the extracted content for each respective sticky-back paper note of the identified overlapping sticky-back paper notes with a corresponding digital note of the plurality of digital notes that represents the respective sticky-back paper note; and automatically grouping the plurality of digital notes based upon the one or more physical grouping indicators detected from the input image. receiving, by a computing device, an input image of an environment having a plurality of overlapping sticky-back paper notes, wherein each of the plurality of sticky-back paper notes comprises a body having a background color and a border around the body having a border color different from the background color, and wherein the input image comprises one or more physical grouping indicators indicating a physical grouping of the plurality of sticky-back paper notes; processing the input image with the computing device to apply a color segmenting process to identify, based on the background color and the border color of each of the overlapping sticky-back paper notes, boundaries for each of the overlapping sticky-back paper notes in the input image; processing the identified borders of each of the overlapping sticky-back paper notes to extract content for each of the respective overlapping sticky-back paper notes, wherein the extracted content for a respective sticky-back paper note includes at least a portion of the body and portions of the border of the respective sticky-back paper note; generating, by the computing device, a plurality of digital notes, each of the digital notes corresponding to one of the identified overlapping sticky-back paper notes; associating, by the computing device, the extracted content for each respective sticky-back paper note of the identified overlapping sticky-back paper notes with a corresponding digital note of the plurality of digital notes that represents the respective sticky-back paper note; and automatically grouping the plurality of digital notes based upon the one or more physical grouping indicators detected from the input image.
