The paper presents a novel method, Zero-Reference Deep Curve Estimation (Zero-DCE), which formulates light enhancement as task of image-specific curve estimation with deep network. Our method trains lightweight network, DCE-Net, to estimate pixel-wise and high-order curves for dynamic range adjustment given image. is specially designed, considering pixel value range, monotonicity, differentiability. Zero-DCE appealing in its relaxed assumption on reference images, i.e., it does not require...
Images captured under water are usually degraded due to the effects of absorption and scattering. Degraded underwater images show some limitations when they used for display analysis. For example, with low contrast color cast decrease accuracy rate object detection marine biology recognition. To overcome those limitations, a systematic image enhancement method, which includes an dehazing algorithm algorithm, is proposed. Built on minimum information loss principle, effective proposed restore...
Underwater vision suffers from severe effects due to selective attenuation and scattering when light propagates through water. Such degradation not only affects the quality of underwater images but limits ability tasks. Different existing methods which either ignore wavelength dependency or assume a specific spectral profile, we tackle color distortion problem image new view.

Rapid development of affordable and portable consumer depth cameras facilitates the use information in many computer vision tasks such as intelligent vehicles 3D reconstruction. However, map captured by low-cost sensors (e.g., Kinect) usually suffers from low spatial resolution, which limits its potential applications. In this paper, we propose a novel deep network for super-resolution (SR), called DepthSR-Net. The proposed DepthSR-Net automatically infers high-resolution (HR) low-resolution...
During recent years, we have witnessed a rapid development of wireless network technologies which revolutionized the way people take and share multimedia content.

Underwater object detection is a crucial and challenging problem in marine engineering aquatic robotics. The difficulty partly because of the degradation underwater images caused by light selective absorption scattering. Intuitively, enhancing can benefit high-level applications like detection. However, it still unclear whether all detectors need image enhancement as preprocessing. We therefore pose questions <italic xmlns:mml="http://www.w3.org/1998/Math/MathML"...
As an important and challenging problem in computer vision, zero-shot learning (ZSL) aims at automatically recognizing the instances from unseen object classes without training data. To address this problem, ZSL is usually carried out following two aspects: 1) capturing domain distribution connections between seen data 2) modeling semantic interactions image feature space label embedding space. Motivated by these observations, we propose a bidirectional mapping-based relationship scheme that...

Instead requiring projection function information across modalities like most previous work, LSE...
