FEATURE PROCESSING METHOD AND DEVICE FOR MOTION TRAJECTORY, AND COMPUTER STORAGE MEDIUM

摘要

A feature processing method and device for a motion trajectory, and a computer storage medium. The method comprises: a client acquires a motion trajectory generated by a user behavior to obtain a string of ordered point set, and each trajectory point in the ordered point set comprises a position element and a time element; use information in the position element and the time element to convert the motion trajectory into an image; and by performing image processing on the image, obtaining one or more feature vectors in the motion trajectory.
