Abstract: Systems and methods for generating random bits by using physical variations present in material samples are provided. Initial random bit streams are derived from measured material properties for the material samples. In some cases, secondary random bit streams are generated by applying a randomness extraction algorithm to the derived initial random bit streams.

Abstract: Techniques for creating and manipulating software notes representative of physical notes are described. A computing device includes a processor, an image collection module executable by the processor and configured to receive an input image of an environment having a plurality of overlapping physical notes, and an image processing engine executable by the processor and configured to process the input image with the computing device to identify the plurality of overlapping physical notes in the input image. The image processing engine determines a boundary of each note in the plurality of overlapping physical notes in the input image, and generates a plurality of digital notes corresponding to the determined boundary of each of the overlapping physical notes identified in the input image.

Abstract: 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.
