1. An architecture for real-time extraction of extended maximally stable extremal regions (X-MSERs) comprising a communication interface and processing circuitry adapted in hardware to in real-time:

  • receive a data stream of an intensity image via the communication interface;

    receive a data stream of a depth image via the communication interface;

    find intensity extremal regions within the intensity image;

    find depth extremal regions within the depth image;

    determine strong extremal regions based upon significant overlap between the intensity extremal regions and the depth extremal regions; and

    determine X-MSER ellipses parameters based upon the strong extremal regions and X-MSER criteria.
