Efficient Semantic Segmentation by Altering Resolutions for Compressed Videos
Yubin Hu, Yuze He, Yanghao Li +4
Video semantic segmentation (VSS) is a computationally expensive task due to the per-frame prediction for videos of high frame rates. In recent work, compact models or adaptive net…
Novel tile segmentation scheme for omnidirectional video
Jisheng Li, Ziyu Wen, Sihan Li +3
Regular omnidirectional video encoding technics use map projection to flatten a scene from a spherical shape into one or several 2D shapes. Common projection methods including equi…
Learning to Estimate Kernel Scale and Orientation of Defocus Blur with Asymmetric Coded Aperture
Jisheng Li, Qi Dai, Jiangtao Wen
Consistent in-focus input imagery is an essential precondition for machine vision systems to perceive the dynamic environment. A defocus blur severely degrades the performance of v…
Learning to compose 6-DoF omnidirectional videos using multi-sphere images
Jisheng Li, Yuze He, Yubin Hu +2
Omnidirectional video is an essential component of Virtual Reality. Although various methods have been proposed to generate content that can be viewed with six degrees of freedom (…
Online Multi-modal Person Search in Videos
Jiangyue Xia, Anyi Rao, Qingqiu Huang +3
The task of searching certain people in videos has seen increasing potential in real-world applications, such as video organization and editing. Most existing approaches are devise…
Learning Model-Blind Temporal Denoisers without Ground Truths
Yanghao Li, Bichuan Guo, Jiangtao Wen +3
Denoisers trained with synthetic data often fail to cope with the diversity of unknown noises, giving way to methods that can adapt to existing noise without knowing its ground tru…
A Generalized Rate-Distortion- Model Based HEVC Rate Control Algorithm
Minhao Tang, Jiangtao Wen, Yuxing Han
The High Efficiency Video Coding (HEVC/H.265) standard doubles the compression efficiency of the widely used H.264/AVC standard. For practical applications, rate control (RC) algor…
Long and Diverse Text Generation with Planning-based Hierarchical Variational Model
Zhihong Shao, Minlie Huang, Jiangtao Wen +2
Existing neural methods for data-to-text generation are still struggling to produce long and diverse texts: they are insufficient to model input data dynamically during generation,…
Two-pass Light Field Image Compression for Spatial Quality and Angular Consistency
Bichuan Guo, Jiangtao Wen, Yuxing Han
The quality assessment of light field images presents new challenges to conventional compression methods, as the spatial quality is affected by the optical distortion of capturing…
Fast Block Structure Determination in AV1-based Multiple Resolutions Video Encoding
Bichuan Guo, Yuxing Han, Jiangtao Wen
The widely used adaptive HTTP streaming requires an efficient algorithm to encode the same video to different resolutions. In this paper, we propose a fast block structure determin…
Convex Optimization Based Bit Allocation for Light Field Compression under Weighting and Consistency Constraints
Bichuan Guo, Yuxing Han, Jiangtao Wen
Compared with conventional image and video, light field images introduce the weight channel, as well as the visual consistency of rendered view, information that has to be taken in…
A Bayesian Approach to Block Structure Inference in AV1-based Multi-rate Video Encoding
Bichuan Guo, Xinyao Chen, Jiawen Gu +2
Due to differences in frame structure, existing multi-rate video encoding algorithms cannot be directly adapted to encoders utilizing special reference frames such as AV1 without i…
LSTM-Based Facial Performance Capture Using Embedding Between Expressions
Hsien-Yu Meng, Tzu-heng Lin, Xiubao Jiang +2
We present a novel end-to-end framework for facial performance capture given a monocular video of an actor's face. Our framework are comprised of 2 parts. First, to extract the inf…
An Efficient and Integrated Algorithm for Video Enhancement in Challenging Lighting Conditions
Xuan Dong, Jiangtao, Wen +6
We describe a novel integrated algorithm for real-time enhancement of video acquired under challenging lighting conditions. Such conditions include low lighting, haze, and high dyn…
