PROGRESSIVE PATTERN-RECOGNITION USING THE WAVELET TRANSFORM

This paper discusses a technique for performing wavelet-based pattern recognition. Known as 'progressive pattern recognition', this approach is based on performing a subband decomposition of a target image usin g the two-dimensional discrete wavelet transform and then performing p artial correlations with different subband resolutions. This approach offers the possibility of recognizing the image without having to perf orm a full correlation of the image or of its complete wavelet transfo rm, with the potential for considerable savings in computational time. The algorithm for the progressive pattern recognition is presented wi th results obtained from computer simulations of hand-print recognitio n.
