Pattern recognition system
专利汇可以提供Pattern recognition system专利检索，专利查询，专利分析的服务。并且PURPOSE: To realize decision at high speed and with high accuracy, by eliminating the influence of noise, learning position shift and the fluctuation of line width by extracting a projective vector, and performing feature extraction to enhance a difference between the categories of a character pattern based on discriminant analysis.
CONSTITUTION: A pattern storage means 10 reads out a storing unknown pattern (f), and a character frame detecting means 20 performs the detection of the character part of the unknown pattern (f). A projection operating means 30 calculates the sums x
i and x
j of density values within the character frame in a horizontal and a vertical directions. When the operation of a projective value storage means 40 is completed, a linear unifying arithmetic part 80 reads out a linear unifying matrix from a linear unifying matrix storage part 50, then performs linear unification. The result of the linear unification is sent to a deflection correcting arithmetic part 90, and the deflection correcting arithmetic part 90 reads out a deflection correcting vector from a deflection correcting vector storage part 60, then, performs deflective correction. After completing the deflective correction, a similarity arithmetic part 100 reads out a reference vector from a reference vector storage part 70, and computes similarity. Obtained similarity is sent to a classifying means at the next stage.
