1. A gesture recognition system for remote control of a device, comprising:

  • (a) a sensor for capturing video data of a user'"'"'s hand at a location near the device;

    (b) a processor for processing the captured video data of the hand; and

    (c) programming executable on said processor for carrying out steps comprising;

    segmenting each hand image in the captured video based on skin color;

    extracting one or more parameters of the segmented hand image;

    wherein the one or more parameters comprises a palm center location of the user'"'"'s hand based on an extracted contour and skeleton of the hand;

    wherein said palm center location comprises a center of the user'"'"'s palm during an “

    configuration corresponding to a condition wherein all of the user'"'"'s fingers are extended to expose the user'"'"'s palm;

    wherein the one or more parameters further comprises a palm bottom location;

    measuring the distance between the palm center location and a furthest contour point on the extracted image contour;

    the furthest contour point being within a predetermined angular range of a vector passing through the palm bottom location and the palm center location;

    tracking the one or more parameters in the hand image;

    classifying a hand gesture as “

    open”

    or “

    closed”

    based on the one or more parameters; and
