Motion Compensated Frame Rate Up-Conversion for Low Frame Rate Video

2006
Frame rate up-conversion is useful for low frame rate pictures such as movie. In case of conversion, basic motion compensation causes gap at covered area and uncovered area. To avoid the gap, we propose the motion compensation centered at the position of target. Fully motion compensated interpolation is possible in this method.

Occlusion artifact removal in video frame rate up-conversion

2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009
In the past, frame rate up-conversion (FRC) methods were commonly used in standards conversion. Today, FRC methods are used for digital video temporal resolution enhancement to improve the visual quality in large screen LCD and plasma TV sets. The increase in processing power of DSPs, FPGAs and ASICs enables high complexity algorithms in the design of ...

Motion vector processing for frame rate up conversion

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
In this paper, the effect of motion vector accuracy on the efficiency of motion compensated frame rate up conversion (MC-FRUC) is studied. The motion vector processing problem is formulated and analyzed via motion vector modelling. A processing scheme is proposed to improve the interpolated frame quality at the decoder.

Frame Rate Up-Conversion Based on Edge Information

2019 7th International Conference on Information, Communication and Networks (ICICN), 2019
This paper proposes a Frame Rate Up-Conversion method based on edge information which synthesize edge information with the motion estimation and motion compensation. The proposed method uses variable block motion estimation for accuracy motion vector field, and improves the image quality via edge information. Experimental results show that the proposed

Frame rate up-conversion using the wavelet transform

2000 Digest of Technical Papers. International Conference on Consumer Electronics. Nineteenth in the Series (Cat. No.00CH37102), 2002
We propose a new frame rate upconversion algorithm using the wavelet transform. In the proposed scheme, motion estimation is performed using the information in the wavelet-transformed subbands. In addition, an effective compensation method for the occlusion areas, called overcompensation, is presented.

Dual Motion Estimation for Frame Rate Up-Conversion

IEEE Transactions on Circuits and Systems for Video Technology, 2010
In this letter, we present a new motion estimation algorithm for frame rate up-conversion. The proposed dual motion estimation algorithm enhances the estimation accuracy of motion vectors by using the unidirectional and bidirectional matching ratios of blocks in the previous and current frames.

Frame rate up-conversion with nonlinear temporal interpolation

2012 5th International Congress on Image and Signal Processing, 2012
Motion compensated frame rate up-conversion (MCFRUC) partly resolves some of the issues in video interpolation such as blurred images resulting from incorrect linear motion interpolation and motion jerkiness caused by frame repetition. Most of the block artifacts and incorrect interpolated frames are caused by linear-motion-based FRUC.

Robust video frame rate up-conversion (FRUC) techniques

2009 Digest of Technical Papers International Conference on Consumer Electronics, 2009
Two challenging situations for video frame rate up-conversion (FRUC) are first identified; namely, when the input video has abrupt illumination change and/or a low frame rate. Then, a low-complexity robust FRUC algorithm is proposed to address these two issues.

Video frame rate up conversion under inconsistent camera

SPIE Proceedings, 2006
In this paper, we address the problem of video frame rate up conversion (FRC) in compressed domain. FRC is often recognized as video temporal interpolation. The problem is very challenging when targeted for a video sequence with an inconsistent camera and object motion.

A novel method for frame rate up-conversion

2011 International Conference on Image Analysis and Signal Processing, 2011
In this paper, we proposed a new motion compensated interpolation (MCI) algorithm for frame rate up-conversion (FRUC) in multimedia applications. First, we propose the bilateral motion estimation (ME) scheme to obtain the motion field of an interpolated frame without yielding the hole and overlapping problems. Secondly, we partition the block which the
