Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. A system for feature processing, comprising:
one or more processors;
a computer readable storage medium coupled to at least one of the processors; and
computer code stored on the computer readable storage medium, with the computer code including instructions for causing at least one of the processors to perform operations including the following:
projecting two input image recognition features selected from multiple features of each sample in a sample set to one resulting feature based on a specified curve, wherein the projecting the two input image recognition features comprises:
projecting a two-dimensional data point to a one-dimensional data point on the specified curve, wherein two values of two axes of the two-dimensional data point in a coordinate system are respectively determined from the two input image recognition features, and the one-dimensional data point is a data point on the specified curve which has the shortest distance to the two-dimensional data point as an orthogonal distance, and
determining an arc length from the one-dimensional data point to a start point in the specified curve as the resulting feature,

updating the sample set by replacing the two input image recognition features with the one resulting feature for each sample in the sample set, and
repeating the projecting and the updating for the sample set until the number of features of each sample in the sample set reaches a predetermined criterion.
