Research output: Contribution to journalConference articlepeer-review


This paper proposes an algorithm to find the region of interest (ROI) by using motion vector from the encoded bit-stream and perform frame rate up conversion (FRUC). First, the motion vector (MV) in the frame is collected by decoding the bit-stream and the ROI is defined in the frame based on the MV. The interpolated frame is created by reusing MV, which enables compact operations. The proposed method can provide a more comfortable visual experience to the user by performing FRUC using decoding information of the video bitstream. The proposed technique effectively resolves the artifact and shows an excellent visual quality and execution speed compared to the block based motion compensated algorithms.
