Directional Coherence-Based Scrolling-Text Detection for Frame Rate Up-Conversion

open access: yesIEEE 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 ...

Using Noise Level to Detect Frame Repetition Forgery in Video Frame Rate Up-Conversion [PDF]

open access: yesFuture 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

Luminance Level of Histogram-Based Scene-Change Detection for Frame Rate Up-Conversion

open access: yesIEEE 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.

Frame-rate up-conversion detection based on convolutional neural network for learning spatiotemporal features

open access: yesForensic Science International, 2022
With the advance in user-friendly and powerful video editing tools, anyone can easily manipulate videos without leaving prominent visual traces. Frame-rate up-conversion (FRUC), a representative temporal-domain operation, increases the motion continuity of videos with a lower frame-rate and is used by malicious counterfeiters in video tampering such as

Adaptive luminance coding-based scene-change detection for frame rate up-conversion [PDF]

open access: yesIEEE Transactions on Consumer Electronics, 2013
This paper presents a new scene-change detection method that uses adaptive luminance coding for frame rate up-conversion. The proposed scene-change detection method splits a frame into several blocks and converts the gray levels of pixels in each block to bit codes.

Frame Rate Up-Conversion with Occlusion Detection Function

open access: yesJournal of Broadcast Engineering, 2015
A new technology on video frame rate up-conversion (FRUC) is presented by combining the median filter and motion estimation (ME) with an occlusion detection (OD) method. First, ME is performed to have a motion vector. Then, the OD method is used to refine motion vector in the occlusion region.

Mid-IR Luminosities and UV/Optical Star Formation Rates at z<1.4 [PDF]

open access: yes, 2009
UV continuum and mid-IR emission constitute two widely used star formation indicators at intermediate and high redshifts. We study 2430 galaxies with z10^11 L_sun, yet with little current star formation. For them a reasonable amount of dust absorption of
