Title
Selective Data Pruning Based Distributed Video Coding With Modified High-Order Edge-Directed Interpolation
Abstract
In distributed video coding (DVC), a low resolution video sequence is usually generated with spatial and/or temporal downsampling at an encoder. At a decoder side, interpolation is performed and the interpolated pixels are further refined by using an error-correcting code such as Turbo codes or LDPC. In our previous work, we proposed a spatial domain DVC which uses a line-based downsampling method called selective data pruning (SDP). SDP is used for reducing the spatial frame size before compression. After decoding, received frames are decoded and interpolated back to their original size by high-order edge-directed interpolation (HEDI). In this paper, we propose a modified high-order edge-directed interpolation (M-HEDI) to avoid interpolation artifacts. Experimental results show that the interpolated frames by using M-HEDI have higher quality than those using HEDI. The proposed method outperforms conventional DVCs and the video coding standard H.264/AVC in majority of all the test video sequences.
