  • Patent number: 11055881
    Abstract: The present invention discloses a system and a method for providing color vision deficiency assistance by selectively recoloring pixels of an image frame including unperceivable colors with perceivable colors in real time. In particular, the present invention provides for rescaling the image frame using a first set of rules. Further, a perceivable color space is selected based on one or more parameters. Furthermore, one or more pixels associated with unperceivable colors are identified using a second set of rules. Yet further, the identified one or more pixels are recolored using the selected perceivable color space and a third set of rules. Finally, a corrected image frame comprising perceivable colors is provided.
    Type: Grant

  • Patent number: 9411837
    Abstract: The present disclosure generally relates to database management and, more particularly, to systems and methods for optimizing memory utilization of the database. In one embodiment, a method for optimizing memory utilization in a database is disclosed. The method comprises designating a first quantitative value of the plurality of quantitative values as a first epoch associated with a first tuple; determining a first difference between a second quantitative value of the plurality of quantitative values and the first epoch; storing the first difference as a second delta value associated with a second tuple when an absolute value of the first difference is less than a threshold; designating the second quantitative value as a second epoch associated with the second tuple when the absolute value of the first difference is greater than or equal to the threshold; and generating a master tuple.
