Abstract:
1. An object identification system for tracking a moving object in an image frame by analysis of an input signal, based upon user specified criteria for identifying such moving object, the object identification system comprising: an image processing system for generating a first output signal including information related to the user specified criteria regarding the moving object, the image processing system including a temporal processing unit for smoothing the input signal and, in turn, generating a first interim signal, a memory associated with the temporal processing unit, a delay unit for introducing a delay to the first interim signal, a spatial processing unit for receiving the first interim signal with the delay from the delay unit and producing a second interim signal, and a sequencing unit for processing the second interim signal and generating the first output signal; and a histogram processor for processing the first output signal, received from the image processing system, and generating a second output signal containing information about the object in the image frame, the histogram processor including a histogram forming portion configured for receiving the first output signal and forming a histogram therefrom, a classifier for selecting the user specified criteria of a given pixel within the image frame for which the histogram is to be formed, a validation block for determining whether the given pixel within the image frame will be used in forming the histogram, and a key characteristics unit for computing key characteristics for the histogram, wherein the histogram forming portion receives the first output signal and, in cooperation with the classifier, the validation block, and the key characteristics unit, generates the second output signal identifying the moving object in the image frame.
