1. A method for processing video data, the method comprising:

  • generating one or more motion vectors based on extracted picture rate up-conversion (PRUC) data by minimizing a cost function, wherein said cost function is constrained by one or more of;

    a block matching constraint, a smoothness constraint and/or a bias constraint, wherein said block matching constraint is represented as
