- Block-wise processing of motion compensated interlaced-to-progressive conversion (MC-IPC) can cause spurious errors that degrade converted image quality significantly. This paper presents a novel IPC method based on motion adaptive IPC (MA-IPC) with its adaptation assisted by the motion compensation. The motion adaptation is performed with respect to a motion selected from a limited set based on the accuracy evaluated with a reduced and overlapped block. The use of the reduced and overlapped blocks makes evaluation of the accuracy more precise, and implementation less costly. The motion adaptation structure ensures that any possible error occurs pixel-wise so that the block-wise spurious errors can be eliminated. The estimation of the motion is performed efficiently with data already available for the motion adaptation. The proposed motion compensation assisted MA-IPC method provides image quality similar to the MC-IPC, for those images, the MC-IPC offers significant improvement over the MA-IPC, yet at considerably lower computational and implementation costs.
