A STUDY OF CHARACTER RECOGNITION PARAMETER ANALYSIS

摘要

An adaptive measurement technique for classifying the quality of printed text encountered in applications of optical print reading machines is presented. The measurement technique utilizes the learning properties of adaptive threshold logic. The convergence rate of the adaptive process is taken as a figure-of-merit for classifying print quality. Rapid con¬vergence is associated with good quality printing while slow convergence is an indication of poor quality. A review of adaptive threshold logic is presented as an aid for describing the measurement technique.
