Abstract
In this paper, we propose a frame rate up-conversion (FRUC) method using the motion compensation (MC) based on block matching algorithm (BMA). The property of the BMA is changed by the size of block. It is desirable for small moving object to set block size small. On the other hand, we would like to set the block size large in the global motion region. Therefore, the block size is decided depend on the property of the local region of frame image. In this paper, we present a novel FRUC technique based on the motion compensated interpolation with multi-size blocks. At first, the frame image is divided into 8x8 blocks and motion vectors are estimated for each 8x8 block. Next, the similar motion blocks are merged into one block, up to 32x32 block. Thus the proposed method reduces block artifacts and realizes the clear interpolation of moving objects regardless of the size of those.
