1. A method of collecting content of notes, comprising: capturing, by a sensor of a computing device, an image, comprising a visual representation of a scene having a plurality of physical notes, each of the physical notes comprising a separate physical object having a predefined boundary and recognizable content thereon; processing, by a processing unit of the computing device, image data associated with the image to identify a predefined boundary of one of the plurality of physical notes from the visual representation; extracting, by the processing unit and based at least in part on identifying the predefined boundary, from the image data the recognizable content from within the predefined boundary of the one of the plurality of physical notes and based at least in part on a contrast between the recognizable content and a background of the one of the plurality of physical notes from the visual representation; and associating the recognizable content with a digital representative of the one of the plurality of physical notes.
