Vector Rational Interpolation Schemes for Erroneous Motion Field Estimation Applied to MPEG-2 Error Concealment

Abstract: Abstract-A study on the use of vector rational interpolation for the estimation of erroneously received motion fields of MPEG-2 predictively coded frames is undertaken in this paper, aiming further at error concealment (EC). Various rational interpolation schemes have been investigated, some of which are applied to different interpolation directions. One scheme additionally uses the boundary matching error and another one attempts to locate the direction of minimal/maximal change in the local motion field neig… Show more

“…Any TEC method can estimate more than one MV for each missing MB by applying the matching measure calculation on a sub-block basis as is done in [34,42]. Multiple MVs can also be estimated by the motion field interpolation methods of [50][51][52][53][54][55][56]. Deng [39] utilizes the detected edge directions to identify whether the lost MB contains multiple objects and decide on how to best conceal partitions (sub-blocks) of it.…”

“…We use control grid interpolation (CGI) [4] to create a MV that satisfy the motion field smooth criterion. For that block, we use the MV of the neighboring block as control points and interpolate MV of each pixel in the block with the spatial displacement in linear estimation process in two directions respectively…”

“…It exploits the redundant information in the previous decoded frame and current correctly received frame to estimate the motion vector (MV) of the lost area and conceal the missing data with the corresponding intensity information. Although TEC techniques have been extensively studied [2][3][4][5], they usually are not suitable for concealing of the loss of a complete video frame. When transmitting low resolution sequences at low bit rate, it is common that one video frame will be compressed to smaller size and can be filled into one transfer unit of the network or channel for the video communication.…”
