Abstract

According to an embodiment, a feature calculation device includes an obtaining unit, a first calculator, and a second calculator. The obtaining unit is configured to obtain a point sequence group comprising a set of point sequences in which a sequence of a plurality of points is fixed. The first calculator is configured to, for each of the point sequences in the point sequence group, calculate a plurality of values related to a curvature of a shape of the point sequence, with a reference point of the point sequence as a reference, and calculate feature quantities based on the plurality of calculated values. The second calculator is configured to calculate a histogram representing a distribution of the feature quantities of each of the point sequences.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2012-286047 filed on December 27, 2012; the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments described herein relate generally to feature computation apparatus and feature computation methods. Background technique [0004] A technique in which the shape of a single stroke of a character or figure handwritten by a user is characterized by the curvature of the shape is known. [0005] In the above-mentioned conventional technology, at each point constituting the point sequence, the expected value of the curvature of the shape identified by the point sequence is calculated with this point as a reference; and the feature quantity representing the dimension of the points constituting the point sequence is extracted, In order to characterize the shape recognized by the point...
