Abstract
A previously reported two-dimensional adaptive Y/C separation and picture enhancement technique is improved. One mode of filtering has been added to selected picture areas in which picture degradations were observed. The lack of sharpness in picture details and picture degradation because of an incorrect choice of filter characteristics have been remedied. The investigation was carried out through computer simulations and hardware implementation
