Abstract
A method and a system implementing the method for detecting presence of burnt-in text in a video sequence are described. Initially, possible text candidates are separated from the background information. Individual candidates are then validated against the character features like similar font width, resolution, width height ratio, etc. These characters are further validated for the formation of words/sentences. Finally, the temporal features are used for validation for determining valid burnt-in text candidates.
