Adaptive frame rate up-conversion based on motion classification

Signal Processing, 2008
In this paper, a new technique on video frame rate up-conversion (FRUC) is presented by combining the adaptive motion classification (AMC) for image sequences and the mixed motion estimation (ME). In the proposed FRUC scheme, the AMC classifies sequences into global and local motion sequences (G/LMS) whose advantages are fully utilized.

Frame rate up-conversion for high-definition video applications

IEEE Transactions on Consumer Electronics, 2013
In this paper, a novel frame rate up-conversion (FRUC) scheme to achieve better visual quality for high-definition videos is proposed. The proposed algorithm has three main advantages over conventional FRUC algorithms. First, to increase the accuracy of motion estimation, this paper considers the diversity of motions, the retiming motion vectors of the

Fractional frame rate up-conversion using weighted median filters

IEEE Transactions on Consumer Electronics, 1989
The authors present algorithms for increasing the frame rate of an interlaced television system by a factor of 1.5. The algorithms utilize a weighted median filter structure and a simple motion detector. By adjusting the weights among the incoming fields the algorithms can be used with noninteger conversion factors.

Adaptive motion-compensated interpolation for frame rate up-conversion

IEEE Transactions on Consumer Electronics, 2002
We propose a new frame rate up-conversion (FRC) algorithm using the adaptive motion compensation (MC) that reduces the blocking artifacts due to block-based processing. In the proposed scheme, after conventional motion estimation (ME) between two adjacent frames is performed to construct the motion vectors for the frame to be interpolated, the motion ...

Video frame rate up conversion under inconsistent camera motion

Multimedia Tools and Applications, 2007
In this paper, we address the problem of video frame rate up-conversion (FRC) in the compressed domain. FRC is often recognized as video temporal interpolation. This problem is very challenging when targeted for video sequences with inconsistent camera and object motion, such as sports videos.

Frame Rate Up-Conversion for Depth-Based 3D Video

2012 IEEE International Conference on Multimedia and Expo, 2012
A novel frame rate up-conversion (FRUC) scheme for depth-based 3D video is proposed. Differing from the existing conventional FRUC methods which are designed for two dimensional (2D) video only, the proposed method is designed for depth-based 3D video, which increases the frame rate of both color sequences and its associated depth maps by jointly ...

Frame Rate Up-Conversion Method for Video Processing Applications

IEEE Transactions on Broadcasting, 2014
In this paper, a new low-complexity frame rate up-conversion (FRUC) method is proposed for video processing applications. In the proposed FRUC method, true motion estimation (TME) is used to track motion trajectories by imposing smoothness constraints on block-matching algorithm (BMA).

A Spatio-Temporal Autoregressive Frame Rate Up Conversion Scheme

2007 IEEE International Conference on Image Processing, 2007
A spatio-temporal autoregressive model is proposed in this paper to address the problem of frame rate up conversion. Every pixel in a skipped frame is generated as a linear combination of pixel values from forward and backward reference frames. At the beginning of the presented scheme, the coarse model parameters are computed according to the given ...
