Abstract:
1. A method for performing image analysis functions in image processing circuitry, comprising: (a) capturing a sequence of high-resolution frames through a wide-angle non-perspective optical train; (b) reducing the pixel resolution of at least some frames in said sequence to thereby produce reduced resolution frames, using a procedure which reduces a pixel count of selected transitory image portions corresponding to imaged objects, wherein the selected image portions corresponding to small-appearing objects are reduced in resolution less than the selected image portions corresponding to large-appearing objects, wherein the reduction of resolution results in a closer similarity in the size of the selected image portions corresponding to transitory objects and maintains at least a minimum number of pixels for the selected image portions; and (c) performing an image analysis that requires the minimum number of pixels on said reduced resolution frames, and outputting the result of said image analysis.
