Abstract:
A method includes making a first determination as to whether a current pixel has a value which reflects a mosquito noise artifact, and determining whether to apply a filtering process at the current pixel based on a result of the first determination. In addition, or alternatively, a method includes making a second determination as to whether a current pixel has a value which reflects a ringing artifact, and determining whether to apply a filtering process at the current pixel based on a result of the second determination.
