Abstract :
Summary form only given. For feature extraction of target images, partial images of Devanagari script were introduced in a parallel JTC recognition system. It improved the discrimination tolerance significantly by using six times smaller pixel numbers of 25/spl times/25 as compared to the previous 64/spl times/64. The result ensures the throughput acceleration by increasing parallelism while keeping improved discrimination signal quality.
