Title:
プログラム及びクラスタリング装置
Document Type and Number:
Japanese Patent JP7365697
Kind Code:
B2
Abstract:
To provide a program and a clustering device which reduce score errors and variations in scores of a scorer, and enhance score efficiency.SOLUTION: In a clustering device, a processing part includes: a scale image generation part for reducing one handwriting pattern image and generating a plurality of scale images; a feature extraction part for giving each of the images to a learning model, and extracting a symbol position feature concerning appearance positions for each kind of symbols for each of a plurality of scale images; a feature vector generation part for dividing the symbol position feature into the plurality of kinds, and determining appearance probability for each of kinds of the symbols for each of the divisions and generating a feature vector; an integral part for taking a maximum value of appearance probability of the same symbol in the same part of the feature vector generated from each of the plurality of scale images, and generating an integral feature vector; and a classification part for classifying a plurality of handwriting patterns into a plurality of groups based on the integral feature vector generated from each of the plurality of handwriting pattern images.SELECTED DRAWING: Figure 1
