System and method facilitating designing of classifier while recognizing characters in a video

摘要

System(s), method(s) and computer program product to facilitate designing of a hierarchy of feature vectors while recognizing one or more characters in a video are disclosed. A video frame is extracted from a video and is divided into segments. The segments are used to collect one or more features. The features provide preparation of one or more feature vectors. A minimum distance between a test character and a pre-stored character template is calculated. The minimum distance represents closeness between characters. The hierarchy of feature vectors is designed by selecting the one or more feature vectors based on a decreasing order of the minimum distance. The characters are then classified based on the hierarchy of the one or more feature vectors so designed.
