- W1982127951 abstract "Flicker is a common video coding artifact that occurs especially at low and medium bit rates. In this paper we propose a temporal filter-based method to reduce flicker. The proposed method has been designed to be compliant with conventional video coding standards, i.e., to generate a bitstream that is decodable by any standard decoder implementation. The aim of the proposed method is to make the luminance changes between consecutive frames smoother on a block-by-block basis. To this end, a selective temporal low-pass filtering is proposed that smooths these luminance changes on flicker-prone blocks. Furthermore, since the low-pass filtering can incur in a noticeable blurring effect, an adaptive algorithm that allows for limiting the PSNR loss -and thus the blur- has also been designed. The proposed method has been extensively assessed on the reference software of the H.264/AVC video coding standard and compared to a state-of-the-art method. The experimental results show the effectiveness of the proposed method and prove that its performance is superior to that of the state-of-the-art method." @default.
