A Novel and Robust System for Time Recognition of the Digital Video Clock Using the Domain Knowledge

摘要

This paper presents a novel and robust system for recognizing the time of the digital video clock by using the domain knowledge. This system comprises a set of the functions for the time recognition so that the user can conveniently use these functions to recognize the time of digital video clocks or to execute some steps of recognizing time. These functions are novel and robust because they use the novel methods derived from the domain knowledge of the digital video clock. These methods are region second periodicity, global maximum model, digit location model, digit-sequence recognition, and on-the-fly SVM. Experimental results show that both the functions and the system can achieve very high recognition accuracy.
