11. A method of managing notes, the method comprising: receiving, by a processing unit from a sensor, a first image comprising a first visual representation of a scene having a plurality of physical notes, each of the physical notes comprising a separate physical object having a general boundary and recognizable content thereon; identify, by the processing unit, one or more marks associated with the one or more of the plurality of physical notes in the first image; determine, by the processing unit, a location associated with the one or more marks; control, by the Processing unit, based on the location, the sensor to generate a second image comprising a second visual representation of the scene, wherein the second image comprises a zoomed-in image of one or more notes of the plurality of physical notes of the first visual representation of the scene; processing, by the processing unit, image data associated with the image to identify the general boundary of at least one of the plurality of physical notes; authenticating the one of the plurality of physical notes; in response to determining that the one of the plurality of physical notes is authenticated, extracting, by the processing unit and based at least in part on identifying the general boundary, the recognizable content of the one of the plurality of physical notes; and labeling, by the processor, respective digital notes representing each of the plurality of physical notes with a category.
