A method for detecting banding artifacts in digital video content , a device , a program storage device having an application program

摘要

Banding achihuakuto in the digital video contents which have the series of the video picture which moves is identified, method and the system which are sought, forming the mask picture which corresponds to the picture from series of the video picture which moves on the basis of the change of the general gradient, (402), banding a - include the process which detects the latent territory which includes chihuakuto. Value of the mask picture is done and scaling using gradient operator (404), with that, makes banding achihuakuto detection possible. Banding achihuakuto the identification/it is detected next, on the basis of the gradient of section (406).
