An Illustration Image Classication Focusing on Infrequent Colors

IR

Abstract

Illustration images used in comics or animation have a style that constitutes an emotional feature. The style is represented by the various elements of the illustration image. There are a few research studies that treat the style of illustration images. In this paper, we tried to model the style by using an image feature, and to classify an illustration image by style. We thought that the color that appeared infrequently would represent the style of the illustration image. Therefore, we proposed the method for creating the color histogram, which emphasizes colors appearing infrequently. We term this \Infrequency histogram; IF-hist." To test the effectiveness of the histogram, we experimented with classifying two styles defined as “For boys" and “For girls" based on the IF-hist. The results of the experiment indicated that, when using the IF-hist, the precision of the classification result of the style “For girls" is 93%. This is 50% higher than when using the existing normal color histogram. Moreover, the precision of the other classification results has improved.
