A Study on Image Quality Improvement of Interpolated Frames Using Motion Compensation
Details
Recently, a frame interpolation method that uses motion compensation receive attention. However, distortions occurr at the block boundaries because the motion vector is estimated by a block-by-block manner. Consequently, the image quality of the interpolated frame is degraded. In this thesis, we propose an interpolation method using motion estimation for reducing block noises. To improve the image quality, motion compensation blocks are further divided, and a new motion vector is calculated based on reliability criteria for each sub-block and motion vector is estimated by a block that changed phase and frames are interpolated based on those new motion vectors.
