  • Method for performing image processing applications using quadratic programming
    Patent number: 8761533
    Abstract: A method performs an image processing application by expressing the image processing application as a non-negative quadratic program (NNQP) with a quadratic objective, and nonnegativity constraints. A Karush-Kuhn-Tucker condition of the NNQP is expressed as a fixpoint ratio. Then, the fixpoint ratio is determined iteratively until a solution to the image processing application is reached with a desired precision.
