High Frame Rate Video Reconstruction Based on an Event Camera
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019 Event-based cameras measure intensity changes (called ‘events’) with microsecond accuracy under high-speed motion and challenging lighting conditions. With the ‘active pixel sensor’ (APS), the ‘Dynamic and Active-pixel Vision Sensor’ (DAVIS) allows the ...

Auxiliary Task Graph Convolution Network: A Skeleton-Based Action Recognition for Practical Use
Applied SciencesGraph convolution networks (GCNs) have been extensively researched for action recognition by estimating human skeletons from video clips. However, their image sampling methods are not practical because they require video-length information for sampling ...

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 Study of High Frame Rate Video Formats
IEEE transactions on multimedia, 2019 High frame rates are acknowledged to increase the perceived quality of certain video content. However, the lack of high frame rate test content has previously restricted the scope of research in this area—especially in the context of immersive video ...

Multi-Scheme Frame Rate Up-Conversion Using Space-Time Saliency
IEEE Access, 2018 We propose a novel frame rate up-conversion algorithm, which adaptively selects multiple motion estimation (ME) schemes to generate absent frames according to the space-time saliency.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

A Spatial Prediction-Based Motion-Compensated Frame Rate Up-Conversion
Future Internet, 2019 In Multimedia Internet of Things (IoT), in order to reduce the bandwidth consumption of wireless channels, Motion-Compensated Frame Rate Up-Conversion (MC-FRUC) is often used to support the low-bitrate video communication.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Using Noise Level to Detect Frame Repetition Forgery in Video Frame Rate Up-Conversion
Future Internet, 2018 Frame repetition (FR) is a common temporal-domain tampering operator, which is often used to increase the frame rate of video sequences. Existing methods detect FR forgery by analyzing residual variation or similarity between video frames; however, these
