Claim One:
1. A process of tracking a target provided in an input signal received by an image processing system, the image processing system being configured for receiving the input signal, which input signal includes data regarding a succession of frames, and each frame including a plurality of pixels, a portion of the plurality of pixels including the target, the process comprising: calculating a histogram boundary for an area defined within the portion of the plurality of pixels containing the target; analyzing the calculated histogram boundary to determine whether the area contains the target in its entirety; adjusting the histogram boundary for the area defined within the portion of the plurality of pixels containing the target until the adjusted histogram boundary contains the target in its entirety; and setting the calculated histogram boundary based on predefined criteria, wherein the predefined criteria includes coordinates (Xmin, Ymin) and (Xmax, Ymax), and wherein calculating the histogram boundary comprises: calculating an x histogram dimension for pixels from Xmin to Xmax; calculating a y histogram dimension for pixels from Ymin to Ymax; and analyzing the calculated x and y histograms dimension to determine whether the x and y histogram dimensions contain target information, wherein analyzing the x and y histogram dimensions comprises performing a thresholding operation, wherein the area defined by the histogram boundary is defined by coordinates (Xmin, Ymin) and (Xmax, Ymax), and wherein adjusting the location of the center comprises defining a new center of the histogram boundary at coordinate ((Xmin+Xmax)/2, (Ymin+Ymax)/2).
