Estimating height information from a single remote sensing image is a critical component for 3D perception. Recent methods formulate it as a dense height prediction task based on regression loss functions. However, the regression accuracy is limited by the infinite continuous solution space. In this paper, we propose the soft weighted ordinal (SWO) classification loss for height prediction model t...Show More
Boundary information is essential for the semantic segmentation of remote sensing images. However, most existing methods were designed to establish strong contextual information while losing detailed information, making it challenging to extract and recover boundaries accurately. In this article, a boundary-sensitive network (BSNet) is proposed to address this problem via dynamic hybrid gradient c...Show More
Deep learning-based object detectors have been widely adopted in the field of remote sensing imagery interpretation. These detectors heavily depend on the expensive large-scale labeled datasets, while the scarce remote sensing datasets limit the performance. The domain adaptive object detection can alleviate this problem. However, it struggles with the confusing feature’s alignment, damaging the d...Show More
Object detection is a fundamental part of the interpretation of remote sensing imagery. The one-stage object detector has been adopted into this field because of its high computational efficiency. However, this detector suffers from the misalignment among predefined anchor, object, and feature extracted by standard convolution kernel both in spatial and scale. It limits the further improvement of ...Show More
MOF (metal-organic framework) material of Ni2(dobdc) (where dobdc = 1,4-dioxido-2,5-benzenedicarboxylate) nanocrystals is, for the first time, explored as resonant-gravimetric sensing material for CO detection. Due to the ultra-high surface-area and the active metal center-sites, the MOF of Ni2(dobdc) exhibits adsorbing induced high-performance sensing to CO gas. By loading the MOF material onto r...Show More
A novel multi-dimensional nanostructure constructed with three types of nano-building-block is used as electrochemical sensing material to detect trace dopamine which plays as neurotransmitter in body-fluids. For the multi-dimensional multi-level sensing nanostructure construction, nanosheet of graphene oxide (GO) is herein served as nano-substrate. By using hydrothermal method, ZnO nanowires are ...Show More
Based on resonant micro-cantilever measurements, the metal-organic framework (MOF) nano-crystal material of ZIF-8 is, for the first time, identified as an excellent absorbent to capture/fix the automobile exhaust of NO2 in real atmospheric air. By using MEMS resonant cantilever as material evaluation tool, the adsorbing properties of ZIF-8 to NO2 gas have been experimentally examined not only for ...Show More
In this paper, metal-organic framework (MOF) is explored as xylene sensing-material for resonant-cantilever gas sensor. Sensing experiment with the MOF nano-material of HKUST-1 demonstrates that 400 ppb xylene can be detected. This limit of detection (LOD) has been lower than the human olfactory threshold. The sensing mechanism is identified as the interaction between MOF and xylene. The specifici...Show More
As a prerequisite technique, Deep Packet Inspection (DPI) plays a major role to contemporary network security and management. The key of DPI is a repository of protocol fingerprints. However, inferring and maintaining up-to-date fingerprints for various and new protocols is very difficult in order to adapt them to the continuous evolution of the protocols. In this paper, we propose ProDigger, a ro...Show More
In order to recognizing the feature of abnormality in advance and fix the possible dirty data simultaneously, this article proposed a method to construct a proper mode for a production process producing specific product, a method to estimate the stability of a linear process and a group of data cleaning rule. Both the data processing procedure and algorithm are given detailedly with some samples a...Show More
Target tracking has always been a hot research topic in the field of computer vision. Tracking-Learning-Detection (TLD) is a new algorithm for online learning tracking proposed by Zdenek Kalal. In the algorithm, the computation consuming of detection module is relatively large. To solve this problem and improve the algorithm, we proposed an online learning method to adaptively update the threshold...Show More
Nowadays motion detection in video sequences is the basis for the high-level analytics and applications. After ViBe is proposed, the current mainstream detection algorithm is based on pixel level to construct the background model for the foreground / background segmentation. Influenced by this kind of algorithm, this paper proposes a spatiotemporal-based algorithm to construct an approximate preci...Show More
The paper reports a size-effect of graphene-oxide (GO) nano-sheets on sensitivity of chemical-gas detection. By using resonant-cantilevers to measure molecule-adsorbing induced mass, the size-effect is classified as in-plane dimension lateral-effect and vertical thickness-effect. Based on detection of both reducing-gas of NH3 and oxidizing-gas of NO2, this research clearly reveals that, lateral-di...Show More
With the powerful development of pedestrian detection technique based on sliding-window and machine-learning, detection-based tracking systems have become increasingly popular. Most of these systems rely on existing static pedestrian detectors only despite the obvious potential motion information for people detection. This paper proposes a novel pedestrian detection framework fusing static and dyn...Show More
Crowd density estimation is important for intelligent video surveillance. Many methods based on texture features have been proposed to solve this problem. Most of the existing algorithms only estimate crowd density on the whole image while ignore crowd density in local region. In this paper, we propose a novel texture descriptor based on Local Binary Pattern (LBP) Co-occurrence Matrix (LBPCM) for ...Show More
