A system and method are disclosed for effectively utilizing universal feature detectors to generate closely-correlated universal feature information for use in various content-retrieval procedures. In certain embodiments, the universal feature detectors may generate a multi-scale gaussian pyramid based upon selected original image data by iteratively performing a series of summing transforms. The universal feature detectors may also calculate multi-scale histograms corresponding to the multi-scale gaussian pyramid, and may then perform Radon transforms upon the multi-scale histograms to produce and store corresponding Radon transform lines. The universal feature detectors may also generate a multi-scale laplacian pyramid from the multi-scale gaussian pyramid by iteratively performing a series of difference transforms. The resultant universal feature information may then advantageously provide various types of required feature information with optimal binding characteristics.
