Bidirectional motion estimating method and video frame rate up-converting method and system

The invention provides a bidirectional motion estimating method and system. The method comprises, after a prior frame image and a current frame image are obtained, performing bidirectional motion estimation based on forward block matching and backward block matching respectively; then according to the minimum SAD (sum of absolute difference) value and the corresponding motion vector which are obtained respectively, obtaining a final motion vector, wherein the obtained final motion vector can accurately describe the motion status of a moving object and accordingly solve the confusion between the moving object and the background due to inaccuracy of the motion vector. The invention also provides a video frame rate up-converting method and system. The method comprises obtaining the final motion vector according to the bidirectional motion estimating method and system and then performing motion vector filtering, motion compensation and blocking effect treatment; the finally obtained interpolated frames can eliminate confusion between the moving object and the background and blocking effects, improves the image quality of interpolated images, reduces the problems such as smoothness and continuity of video images and improves the visual effects of videos.
