CE9: An early termination of DMVR (Test 9.2.5)
Authors: Takeshi Chujoh Sharp Tomohiro Ikai Sharp
Abstract
This contribution is a report of CE9.2.5. In this contribution, a result of an early termination of DMVR (Decoder Motion Vector Refinement) has been reported. DMVR is a method of improving coding efficiency without explicitly sending overheads by motion vectors refinement of the merge mode on the both encoder and decoder side. One of the tasks is to reduce the complexity of the decoder side. In this contribution, an early termination of DMVR is improved. As experimental results, the decoding time was reduced by 2% without additional SIMD, and the coding loss is 0.04%.
