An intra prediction algorithm is proposed aiming to efficiently encode smooth regions in depth maps. By taking the textureless characteristics of depth maps into account, only one single prediction direction instead of multiple prediction directions is sufficient in intra prediction of depth maps. Consequently, coding of the prediction direction can be skipped which results in lower computational complexity and higher coding efficiency for synthesised views.
