| dc.description.abstract | The goal of the presented work is to apply a directionally-adaptive two-dimensional separable wavelet transform, called directionlets, in common wavelet-based video coders. So far, directionlets have been used only in still image coding, where they have provided a sparser representation of images in the transform domain and a better compression performance. We apply directionlets to frames of video sequences in the video coding scheme based on the Dirac video codec. The novel method outperforms the traditional non-adaptive method based on the standard wavelet transform in terms of both the rate-distortion performance and the visual quality of reconstructed sequences | |
