  9. Summary • Quality of synthesized view depends more on quality of compressed/decompressed image (QP parameter) than on quality of compressed/decompressed depth (QD). • The usual approach of choosing the minimal QP does not give the best results in some cases, but the differences of quality measures are negligible. • Quality of synthesized views in coding experiments is almost equally distributed over quality axes for reference bitrates.
