Highlights:

• We establish a prediction distance model to evaluate the intra prediction accuracy.

• We analyze the prediction accuracy for down-sampling based coding method.

• An adaptive down-sampling and interpolation scheme is proposed.

• The intra prediction mode is utilized to design the proposed method.

• The proposed scheme achieves coding gains with negligible complexity increase.
