Thermal radiation coating with low thermal conductivity and high infrared emissivity are desirable. In this work, a novel rare‐earth aluminate (PrAlO3+δ with rhombohedral structure) was synthesized via solid‐state reaction method, and the corresponding coating was fabricated using atmospheric plasma spraying (APS). The study encompassed an investigation into the phase structure, high‐temperature phase...
Image smoothing is a fundamental technology which aims to preserve image structure and remove insignificant texture. Balancing the trade-off between preserving structure and suppressing texture, however, is not a trivial task. This is because existing methods rely on only one guidance to infer structure or texture and assume the other is dependent. However, in many cases, textures are composed of...
Road detection from images is a challenging task in computer vision. Previous methods are not robust, because their features and classifiers cannot adapt to different circumstances. To overcome this problem, we propose to apply unsupervised feature learning for road detection. Specifically, we develop an improved encoding function and add a feature selection process to obtain robust and discriminative...
Computer vision based road detection is an indispensable and challenging task in many real-world applications such as obstacle detection in autonomous driving. Low-level image features (e.g., color and texture) and pre-trained models are commonly used for this task. In this paper, we propose a simple yet effective approach to detect roads from a single image, which avoids the supervised model training...
Growing popularity of video based applications such as Internet multimedia have a demand for copyright protection and authentication. Digital video watermarking can be applied for this task. Traditional video watermarking methods have been limited to signal processing field and pay less attention on Human Visual System(HVS) model. In this paper, we propose a novel digital video watermarking framework...
Image based road detection is a vital task for many real-world applications such as autonomous driving and obstacle detection. In this paper, we propose a novel method for segmenting the road area based on estimation of horizon line and clustering technology. The key idea is to leverage normalized cross correlation (NCC) to search for the line separating road image. Additionally, we divide the lower...
Image based road detection is a vital task for many real-world applications such as autonomous driving and obstacle detection. The detection of unstructured roads is particularly challenging by reason of blurry road borders, rough road surfaces and varying imaging conditions. In this paper, we propose a simple and effective method for unstructured road detection. The key idea is to consider the whole...
Human-Computer Interaction (HCI) technology has been widely used in recent years. However, how to achieve a good performance is still a real challenge due to several practical factors. In this paper, we propose a new method to browse electronic map through human eyes detection. This method can operate movement and zooming of a map by accurately detecting and locating eyes and analyzing their behaviors...
