High-quality online video with less rebuffering
High-quality online video less rebuffering
2017/8/14
We’ve all experienced two hugely frustrating things on YouTube: our video either suddenly gets pixelated, or it stops entirely to rebuffer.Both happen because of special algorithms that break videos i...
PIXEL-BY-PIXEL ESTIMATION OF SCENE MOTION IN VIDEO
video sequence image processing moving object detection tracking recurrent procedures reverse processing
2017/5/15
The paper considers the effectiveness of motion estimation in video using pixel-by-pixel recurrent algorithms. The algorithms use stochastic gradient decent to find inter-frame shifts of all pixels of...
Reach in and touch objects in videos with “Interactive Dynamic Video”
Reach touch objects videos Interactive Dynamic Video
2016/8/2
We learn a lot about objects by manipulating them: poking, pushing, prodding, and then seeing how they react.We obviously can’t do that with videos — just try touching that cat video on your phone and...
Experimenting with Museum and User Friendly Video Files Distribution Platform on the Web "Volumeone"
Web based video-casting MP4 FLV Web 2.0 intermediary User-oriented
2015/11/11
The platform now called “VOLUMEZERO” (http://www.volumezero.jp) was introduced by a team led by Prof. Junko IWABUCHI of Research Institute for Digital Media and Content, Keio University, Tokyo, Japan ...
3D ENDOSCOPY VIDEO GENERATED USING DEPTH INFERENCE: CONVERTING 2D TO 3D
image processing computer vision 3d endoscopy converting 2d to 3d
2015/1/20
A novel algorithm was developed to convert raw 2-dimensional endoscope videos into 3-dimensional view. Minimally invasive surgeries aided with 3D view of the invivo site have shown to reduce errors an...
Random Partial Paired Comparison for Subjective Video Quality Assessment via HodgeRank ∗
Subjective Video Quality Assessment HodgeRank, Random Graphs Persistence Homology
2011/11/28
Subjective visual quality evaluation provides the groundtruth and source of inspiration in building objective visualquality metrics. Paired comparison is expected to yieldmore reliable results; howeve...
Witsenhausen–Wyner Video Coding
Distributed video coding error resilience syndrome coding.
2011/8/21
Inspired by Witsenhausen and Wyner’s 1980 (nowexpired) patent on “interframe coder for video signals,” thispaper presents a Witsenhausen–Wyner video codec, where themotion-compensated previously decod...
PKU-NEC TRECVid 2011 SED: Sequence-Based Event Detection in Surveillance Video
PKU-NEC Sequence-Based Surveillance Video
2011/7/24
In this paper, we describe our system for surveillance event detection task in TRECVid 2011. We focus on pair-wise events (e.g., PeopleMeet, PeopleSplitUp, Embrace) that need to explore the relationsh...
RATE-SSIM OPTIMIZATION FOR VIDEO CODING
SSIM index rate distortion optimization reduced-reference image quality assessment Lagrange multiplier rate-SSIM optimization
2011/7/24
The structural similarity (SSIM) index has been found to bea good indicator of perceived image quality. In this paper,we propose a rate-SSIM optimization scheme for mode selection in H.264/AVC video c...
Up-sampling Dependent Frame Rate Reduction for Low Bit-rate Video Coding
Up-sampling Dependent Frame Rate Video Coding
2011/7/24
In low bit rate video coding, the frame rate of input sequence can be reduced to the half or even smaller portion by skipping or deleting frames before compression, and then the temporal resolution is...
Mode-Dependent Intra Frame Interpolation for H.264/AVC Compressed Video
Mode-Dependent Intra Frame Interpolation
2011/7/24
In this paper, a mode-dependent intra frame interpolation method is proposed for H.264/AVC compressed video. The intra prediction mode information is taken into account in the interpolation filter des...
Detection and Location of Near-Duplicate Video Sub-Clips by Finding Dense Subgraphs
Near-duplicate video detection Sub-clip location Graph shift
2011/7/24
Robust and fast near-duplicate video detection is an important task with many potential applications. Most existing systems focus on the comparison between full copy videos or partial nearduplicate vi...
A Rotation Invariant Descriptor for Robust Video Copy Detection
CBCD frame-level descriptor rotation invariant HOG
2011/7/24
A large amount of videos on the Internet are generated from authorized sources by various kinds of transformations. Many works are proposed for robustdescription of video, which lead to satisfying ma...
SSIM-INSPIRED DIVISIVE NORMALIZATION FOR PERCEPTUAL VIDEO CODING
SSIM index rate distortion optimization residual divisive normalization H.264/AVC coding
2011/7/18
We propose a perceptual video coding framework based on anSSIM-inspired divisive normalization scheme as an attemptto transform the DCT domain frame prediction residuals toa perceptually uniform space...
