摘要

PPROBLEM TO BE SOLVED: To provide an expression discriminator creation device for creating a discriminator whose recognizing precision is high by efficiently collecting not the intentionally created face but the learning data of natural face expressions. PSOLUTION: This expression discriminator creation device is configured to create an expression discriminator 24 by retrieving image data having a keyword whose relevancy with specific expressions is extremely high as tag information from among image data disclosed on the Internet or the like by a sample image data retrieval part 11, and collecting the image data actually including the face of a person under fixed conditions from among those data, and calculating an image featured value by a featured value calculation part 13 from the face region of the data, and carrying out the machine learning of the image featured value by a discriminator creation part 14.
