Detecting video frame-rate up-conversion based on periodic properties of inter-frame similarity
Multimedia Tools and Applications, 2013Video frame-rate up-conversion is one of the common operations for tampering digital videos in the temporal domain, such as creating fake high-quality videos and splicing two video clips with different frame rates. However, few existing works have been proposed for detecting this form of tampering operation.

Detection of motion-compensated frame-rate up-conversion via optical flow-based prediction residue
Optik, 2020Abstract To increase the temporal continuity of low frame-rate videos, Motion-Compensated Frame-Rate Up-Conversion (MC-FRUC), which is a special frame based video editing manipulation, can be employed to synthesize new intermediate frame between two successive frames.

Detecting video frame rate up-conversion based on frame-level analysis of average texture variation
Multimedia Tools and Applications, 2016Frame rate up-conversion (FRUC) refers to frame interpolation between adjacent video frames to increase the motion continuity of low frame rate video, which can improve the visual quality on hand-held displays. However, FRUC can also be used for video forgery purposes such as splicing two videos with different frame-rates.

Detecting video frame-rate up-conversion based on periodic properties of edge-intensity
Journal of Information Security and Applications, 2016Video frame-rate up-conversion (FRUC) is one of the common temporal-domain operations. From the earlier frame repetition and linear interpolation, FRUC has been developed to motion compensated frame interpolation (MCFI), which effectively overcomes the temporal jerkiness and ghosting shadows.

Scrolling text detection based on region characteristic analysis for frame rate up-conversion
Displays, 2018Abstract This paper proposes a new scrolling text detection method for frame rate up-conversion, which uses a text edge detector and motion vector distribution analysis of the detected text. Existing methods use either edge or motion vector information of an image for scrolling text detection.

Scene Change Detection Using Multiple Histograms for Motion-Compensated Frame Rate Up-Conversion
Journal of Display Technology, 2012In this paper, we propose a new scene change detection method using multiple histograms. The proposed method produces multiple histograms of split blocks for consecutive frames. Then, it computes the optimal threshold value using automatic thresholding based on the Otsu method and decides whether the scene change occurs or not using the difference ...

Frame Rate Up-Conversion Using Motion Vector Angular for Occlusion Detection
2015In this paper, we study on handling the issue of occlusions in frame rate up-conversion (FRUC), which has been widely used to reconstruct high-quality videos presented on liquid crystal display. Depending on different types of occlusion problems, adaptive motion estimation is carried out for reducing computational complexity.

Frame rate up conversion (FRUC) is a method that automatically generates and inserts virtual frames between input frames for smoother video playback. When a simple FRUC is applied to a video clip, the image quality around shot boundaries is severely deteriorated.

In this paper, a novel frame rate up conversion (FRUC) algorithm using modified adaptive extended bilateral motion estimation (MAEBME) with scene change detection is proposed. Conventionally, extended bilateral motion estimation (EBME) carries out bilateral motion estimation (BME) twice on the same region, therefore involves high complexity.
