Claim 11:
12. An apparatus, comprising:
a memory configured to store instructions; and
one or more processors configured to execute the instructions to cause the apparatus to:
determine whether an inter predictor correction is enabled for a coding block; and
when the inter predictor correction is enabled for the coding block, perform the inter predictor correction by:
obtaining a plurality of predicted samples from a top boundary and a left boundary of a predicted block corresponding to the coding block, wherein the predicted samples are within the predicted block;
obtaining a plurality of reconstructed samples from top neighboring reconstructed samples and left neighboring reconstructed samples of the coding block; and
deriving a corrected predicted block based on the plurality of the predicted samples, the plurality of the reconstructed samples and the predicted block,

wherein the one or more processors are configured to execute the instructions to further cause the apparatus to obtain the plurality of the predicted samples and the plurality of the reconstructed samples by:
determining a horizontal position parameter and a vertical position parameter based on a coding mode of the coding block, wherein a value of the horizontal position parameter or a value of the vertical position parameter is equal to 4, 8 or 16;
determining a plurality of horizontal positions based on the horizontal position parameter or determining a plurality of vertical positions based on the vertical position Parameter;
obtaining the plurality of the predicted samples from the top boundary of the predicted block based on the plurality of the horizontal positions or obtaining the plurality of the predicted samples from the left boundary of the predicted block based on the plurality of the vertical positions; and
obtaining the plurality of the reconstructed samples from the top neighboring reconstructed samples based on the plurality of the vertical positions or and obtaining the plurality of the reconstructed samples from the left neighboring reconstructed samples based on the plurality of the vertical positions.
