  • Publication number: 20190312985
    Abstract: Systems and methods for processing digital image data representing multiple views of an object of interest use a sparse set of digital images along with object of interest profiling to provide a photo gallery for evidence-related workflows. Digital images are related to each other on the basis of common objects of interest represented in the images and their orientations within the views depicted in each image. Object of interest profile datasets, including spatial orientation data, enable efficient tracking of photography sessions in which a set of prescribed views of an object of interest are meant to be captured, as well as object-orientation-based photo gallery navigation. The systems recognize of a set of physical gestures that enable a user to intuitively navigate among digital images depicting different views of an object of interest based on how they were physically related to each other when captured.

  • Patent number: 10419067
    Abstract: Apparatus and associated methods relate to a programmable resistor having a resistance iteratively programmed by a calibration control loop. In an illustrative example, the calibration control loop may alternately sample the programmable resistance and a reference resistance by producing a corresponding voltage drop across the resistors. The voltage drops may, for example, be induced by the same constant current source. The calibration control loop may compare the voltage drops with a comparator, for example. In some examples, the comparator may provide a count direction signal to a logic block, generating a calibration code. The calibration code may, for example, be applied to the programmable resistor, such that the resistance of the programmable resistor iteratively approaches the resistance of the reference resistor.
