Low-Complexity Encoding in Block-Based Hybrid Video Codecs by Moving Motion Estimation to Decoder Side
Umeå University, Faculty of Science and Technology, Department of Applied Physics and Electronics. (Embedded Systems Lab)
2014 (English)In: International Journal of Adaptive, Resilient and Autonomic Systems, ISSN 1947-9220, E-ISSN 1947-9239, Vol. 5, no 1, 19-29 p.Article in journal (Refereed) Published
Abstract [en]

In this paper the authors present an approach to provide efficient low-complexity encoding for the block-based video coding scheme. The authors present a method based on removing the most time-consuming task, that is motion estimation, from the encoder. Instead the decoder will perform motion prediction based on the available decoded frame and send the predicted motion vectors to the encoder. The results presented are based on a modified H.264 implementation. The results show that this approach can provide rather good coding efficiency even for relatively high network delays.
