Joint Video Super-Resolution and Frame Interpolation via Permutation Invariance
Sensors, 2023 We propose a joint super resolution (SR) and frame interpolation framework that can perform both spatial and temporal super resolution. We identify performance variation according to permutation of inputs in video super-resolution and video frame ...

Luminance Level of Histogram-Based Scene-Change Detection for Frame Rate Up-Conversion
IEEE Access, 2022 Scene change detection is an essential process of frame rate up-conversion (FRUC). The performance of FRUC highly dependents on the accuracy of scene change detection.

Confidence-based adaptive frame rate up-conversion [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 In this article, we propose a new frame rate up-conversion (FRU) method for temporal quality enhancement. The proposed FRU algorithm employs gradual and adaptive motion estimation based on confidence priority for selecting more accurate motion vectors (MVs).

Directional Coherence-Based Scrolling-Text Detection for Frame Rate Up-Conversion
IEEE Access, 2020 This article proposes a new scrolling-text detection method that uses directional coherence for frame rate up-conversion (FRUC). Most previous methods use either gradient information or motion vector (MV) distribution of the frame for scrolling-text ...

A Stacked Deep MEMC Network for Frame Rate Up Conversion and its Application to HEVC
IEEE Access, 2020 Optical flows and video frame interpolation are considered as a chicken-egg problem such that one problem affects the other and vice versa. This paper presents a stack of deep networks to estimate intermediate optical flows from the very first ...

Frame rate up-conversion in cardiac ultrasound
Biomedical Signal Processing and Control, 2020 Abstract The temporal resolution of echocardiographic sequences affects the interpretation of cardiac motion as well as the viewing experience. Temporal resolution, however, is limited by the propagation velocity of sound in tissue. Altering the acquisition system can improve temporal resolution but normally reduces image quality.

Homography-guided stereo matching for wide-baseline image interpolation
Computational Visual Media, 2021 Image interpolation has a wide range of applications such as frame rate-up conversion and free viewpoint TV. Despite significant progresses, it remains an open challenge especially for image pairs with large displacements. In this paper, we first propose
