A Novel Multi-Stage Motion Vector Processing and Application in Motion Compensated Frame Interpolation
UC San Diego researchers have invented a method for motion vector correction for motion-compensated frame interpolation for 120Hz LCD display, enhanced video decoders, as well as any applications that requires frame rate conversion. The method accomplishes the concept of object motion without complex motion estimation and can eliminate blocking artifact using smaller block size. Moreover, this invention outperforms other conventional methods on both objective and subjective video quality.
