A method of detecting a finger shape, a program thereof, a storage medium of the program, and a system for detecting a shape of a finger.

摘要

PROBLEM TO BE SOLVED: To provide a method for solving an identification problem and an individual difference problem of a contour irregular shape in shape estimation by a 2D approach using a monocular camera.SOLUTION: In a method for detecting a finger shape from a picked-up image of a finger picked-up by an imaging device with an information processing device, the information processing device includes a step, by using a Histogram of Oriented Gradients (HoG) method as an image feature extraction method, for calculating luminance gradient information of a smoothed luminance image as an image feature amount after normalizing the picked-up image to be a normalized picked-up image and subsequently smoothing a luminance image of the normalized picked-up image to be the smoothed luminance image when generating image feature amount data of the picked-up image.
