Unsupervised Deep Features for Privacy Image Classification
Chiranjibi Sitaula, Yong Xiang, Sunil Aryal +1
Sharing images online poses security threats to a wide range of users due to the unawareness of privacy information. Deep features have been demonstrated to be a powerful represent…
Tag-based Semantic Features for Scene Image Classification
Chiranjibi Sitaula, Yong Xiang, Anish Basnet +2
The existing image feature extraction methods are primarily based on the content and structure information of images, and rarely consider the contextual semantic information. Regar…
Explicit Facial Expression Transfer via Fine-Grained Representations
Zhiwen Shao, Hengliang Zhu, Junshu Tang +2
Facial expression transfer between two unpaired images is a challenging problem, as fine-grained expression is typically tangled with other facial attributes. Most existing methods…
Indoor image representation by high-level semantic features
Chiranjibi Sitaula, Yong Xiang, Yushu Zhang +2
Indoor image features extraction is a fundamental problem in multiple fields such as image processing, pattern recognition, robotics and so on. Nevertheless, most of the existing f…
HLO: Half-kernel Laplacian Operator for Surface Smoothing
Wei Pan, Xuequan Lu, Yuanhao Gong +4
This paper presents a simple yet effective method for feature-preserving surface smoothing. Through analyzing the differential property of surfaces, we show that the conventional d…
A Probabilistic Bitwise Genetic Algorithm for B-Spline based Image Deformation Estimation
Takumi Nakane, Takuya Akashi, Xuequan Lu +1
We propose a novel genetic algorithm to solve the image deformation estimation problem by preserving the genetic diversity. As a classical problem, there is always a trade-off betw…
FVNet: 3D Front-View Proposal Generation for Real-Time Object Detection from Point Clouds
Jie Zhou, Xin Tan, Zhiwei Shao +1
3D object detection from raw and sparse point clouds has been far less treated to date, compared with its 2D counterpart. In this paper, we propose a novel framework called FVNet f…
Blur Removal via Blurred-Noisy Image Pair
Chunzhi Gu, Xuequan Lu, Ying He +1
Complex blur such as the mixup of space-variant and space-invariant blur, which is hard to model mathematically, widely exists in real images. In this paper, we propose a novel ima…
Unconstrained Facial Action Unit Detection via Latent Feature Domain
Zhiwen Shao, Jianfei Cai, Tat-Jen Cham +2
Facial action unit (AU) detection in the wild is a challenging problem, due to the unconstrained variability in facial appearances and the lack of accurate annotations. Most existi…
