A neural network model training apparatus for enhancing image detail is provided. The apparatus includes a memory and at least one processor configured to obtain a low quality input image patch and a high quality input image patch, obtain a low quality output image patch by inputting the low quality input image patch to a first neural network model, obtain a high quality output image patch by inputting the high quality input image patch to a second neural network model, and train the first neural network model based on a loss function set to reduce a difference between the low quality output image patch and the high quality input image patch, and a difference between the high quality output image patch and the high quality input image patch. The second neural network model is identical to the first neural network model.

A motion estimation method for video data including frames and an apparatus therefor are provided. The motion estimation method includes determining whether a current frame unit for which motion estimation is to be performed corresponds to a double block, when the current frame unit corresponds to a double block, acquiring a candidate vector set corresponding to a first single block included in the double block, as a candidate vector set of the double block, individually calculating a confidence function value of each candidate vector included in the candidate vector set of the double block, for the first single block and a second single block included in the double block, and acquiring an estimated motion vector of the first single block and an estimated motion vector of the second single block, based on the calculated confidence function value of each candidate vector.

Motion estimation method and apparatus for plurality of frames

The invention relates to a method for protecting a video frame sequence against random and/or burst packet losses, the method comprising: partitioning the video frame sequence into a plurality of interleaved video frame subsequences; independently encoding the plurality of interleaved video frame subsequences by a differential video codec; generating for at least one of the plurality of interleaved video frame subsequences at least one B frame predicted from another one of the plurality of interleaved video frame subsequences; and using the at least one B frame as redundant B frame for protecting the video frame sequence.
