Image processing techniques for blind TV ghost cancellation
Zhichun Lei, P. Appelhans, H. Schröder · 2002
This paper describes a technique to ghosts cancellation without a ghost cancellation reference signal. The existing vertical edges in TV image are used to estimate the channel characteristics. With the estimating results, the coefficients of the equalizer are updated. A method to speed up the convergence is given. The equalizer structure for cancelling all kinds of ghosts is discussed too. A new improved solution is achieved by interpreting the TV synchronisation signal as a genuine edge.
