Frame rate up-conversion using nonparametric estimator

2014 IEEE International Conference on Image Processing (ICIP), 2014
In some applications such as digital video broadcasting, video is transmitted over a low capacity channel with lower frame rates. The lower the frame rate, the jerkier or unevener the video motion would be noticed. To solve this problem, frame rate up conversion (FRUC) is employed to increase the frame rate.

Frame Rate Up-Conversion Using Trilateral Filtering

IEEE Transactions on Circuits and Systems for Video Technology, 2010
Frame rate up-conversion (FRUC) can enhance the visual quality of low frame rate video presented on liquid crystal display. To minimize the difference between a reference block and an interpolated block, an effective FRUC algorithm partitions a large block into several sub-blocks of smaller size and estimates their motions.

Adaptive Temporal Frame Interpolation Algorithm for Frame Rate Up-Conversion

IEEE Consumer Electronics Magazine, 2020
This article presents a novel adaptive temporal frame interpolation (FI) algorithm for frame rate up-conversion with reduced complexity. According to the adaptability criteria in the proposed algorithm, frames with a low temporal activity are interpolated using frame averaging, which significantly decreases the algorithm complexity.

Bidirectional Mesh-Based Frame Rate Up-Conversion

IEEE MultiMedia, 2015
The authors propose a new frame rate up-conversion (FRUC) method for temporal video quality enhancement. To cope with translation as well as scale and rotation changes, the algorithm generates an interpolated frame between two given frames on the basis of bidirectional mesh interpolation (BMI).

Weighted-adaptive motion-compensated frame rate up-conversion

IEEE Transactions on Consumer Electronics, 2003
In this paper, we propose a frame rate upconversion algorithm using the weighted-adaptive motion-compensated interpolation (WAMCI) that reduces the block artifacts due to the failure of motion estimation and block-based processing. The proposed method is based on the interpolation scheme by weighted sum of multiple motion-compensated interpolation (MCI)

Encoder assisted video frame rate up-conversion

2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU), 2011
With the use of motion compensation techniques, video frame rate up-conversion (FRC) achieves sharp and continuous motion representation and hence improves visual quality. However, motion estimation errors create artifacts that degrade the performance of FRC methods.

Solving occlusion in Frame-Rate up-Conversion

2007 Digest of Technical Papers International Conference on Consumer Electronics, 2007
Tracking motion of moving objects in a video scene by the human eye results in a stationary picture on the retina. However, if the motion is irregular, tracking can be difficult, resulting in the perception of motion blur or motion judder. This is a typical result due to the broadcast of film material.

Frame rate up-conversion using perspective transform

IEEE Transactions on Consumer Electronics, 2006
In this paper, we propose a frame rate up-conversion (FRUC) algorithm to increase the temporal resolution of video sequences at the decoder side. First, the proposed algorithm segments a frame into several objects. Then, perspective transforms are used to motion-compensate each object, while the translational block matching algorithm (BMA) is applied ...

A method for motion adaptive frame rate up-conversion

IEEE Transactions on Circuits and Systems for Video Technology, 1996
A frame interpolation algorithm for frame rate up-conversion of progressive image sequences is proposed. The algorithm is based on simple motion compensation and linear interpolation. A motion vector is searched for each pixel in the interpolated image and the resulting motion field is median filtered to remove inconsistent vectors. Averaging along the

Frame Rate Up Conversion Based on Variational Image Fusion

IEEE Transactions on Image Processing, 2014
This paper presents a new framework for motion compensated frame rate up conversion (FRUC) based on variational image fusion. The proposed algorithm consists of two steps: 1) generation of multiple intermediate interpolated frames and 2) fusion of those intermediate frames.
