1. A method comprising:

  • receiving, by one or more processors, an input image;

    identifying, by the one or more processors, a plurality of objects in the input image;

    estimating, by the one or more processors, a local transformation matrix for each of the plurality of objects;

    calculating rectification parameters for the plurality of objects using the local transformation matrix;

    identifying, by the one or more processors, a plurality of candidate rectification parameters using a voting procedure on the rectification parameters for the plurality of objects;

    estimating, by the one or more processors, final rectification parameters based on the plurality of candidate rectification parameters;

    computing, by the one or more processors, a global transformation matrix using the final rectification parameters; and

    performing, by the one or more processors, image rectification on the input image using the global transformation matrix.
