Efficient multiple example based super resolution for symmetric mixed resolution stereoscopic video coding
The proposed SMRSVC model can provide clear bitrate reduction and visual merits.Based on the SMRSVC model, we propose a new super resolution (SR) method.zThe new SR method for the SMRSVC model has superior quality and bitrate performance.z In this paper, we first propose a new symmetric mixed resolution stereoscopic video coding (SMRSVC) model which can provide clear bitrate reduction and visual merits. Based on the newly proposed SMRSVC model, we then propose a quality efficient multiple example based super resolution method. In the proposed super resolution method, the four block examples selected from the forward and backward key frames, the reference super resolved frame, and the interview super resolved frame are referred so as to effectively fuse the high frequency component of the super resolved current block of the downsampled non key frame, and then an enhanced super resolved non key frame is followed. Based on six test stereoscopic video sequences, the experimental results demonstrate that besides the bitrate saving effect, the proposed super resolution method for the proposed SMRSVC model also has better quality performance in terms of six well known quality metrics when compared with several state of the art methods for the previous asymmetric resolution stereoscopic video coding model and the SMRSVC model.
