1. A method of identifying an object in a feed of images, the method comprising the steps of:

  • a. analyzing a plurality of sequential frames from a feed of frames;

    b. selecting in each frame, one or more unit areas of interest;

    c. applying to each unit area a plurality of detectors, wherein each detector provides a value expressing one aspect of a target object;

    d. assembling data in a sample vector, wherein the data comprises a plurality of components and each component is the individual value outcome of a given detector applied on a given unit area from a given frame; and

    e. evaluating the performance of the sample vector by counting in the vicinity of the sample vector, all vectors known with the target object to form a first count, and counting all vectors known with or without the target object, as acquired during a training phase to form a second count, wherein the ratio of the first count to the second count estimates the probability of the presence of the target object.
