A new discontinuity adaptive depth upsampling method is proposed in order to obtain a high‐resolution depth map. The proposed method adaptively employs both the local minimum filter and the joint bilateral filter according to the variance of the depth map. Thus, it can reduce the over‐blurred depth regions along the depth discontinuities. The experimental results demonstrate the feasibility of the proposed method.
