Motion compensation assisted motion adaptive interlaced-to-progressive conversion

Abstract

This paper presents a novel interlaced-to-progressive conversion (IPC) method based on the 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 the evaluation of the accuracy more precise, and the implementation less costly. The motion adaptation structure ensures that any possible error occurs pixel-wise, so that block-wise spurious error can be eliminated. The estimation of the motion is performed efficiently with data already available for the motion adaptation. The proposed motion compensation assisted motion adaptive IPC (MoMA-IPC) method provides image quality similar to the motion compensated IPC (MC-IPC) for those images the MC-IPC offers significant improvement over the MA-IPC, yet at the considerably lower computational and implementation cost.
