  • System and method facilitating designing of classifier while recognizing characters in a video
    Patent number: 9117132
    Abstract: The present disclosure relates to designing of a hierarchy of feature vectors. In one embodiment, a method for facilitating design of a hierarchy of feature vectors while recognizing one or more characters in a video is disclosed. The method comprises collecting one or more features from each of the segments in a video frame extracted from a video; preparing multi-dimensional feature vectors to classify the one or more characters; calculating a minimum distance between the multi-dimensional features vectors of a test character and the multi-dimensional feature vectors of a pre-stored character template; selecting, with respect to a decreasing order of the minimum distance, the multi-dimensional feature vectors to design a hierarchy of the multi-dimensional feature vectors; and classifying the characters based on the hierarchy of the multi-dimensional feature vectors.
