Digital route panoramas

Jiang Yu Zheng
2003 IEEE Multimedia  
Route panorama is a new image medium for digitally archiving and visualizing scenes along a route. It's suitable for registration, transmission, and visualization of route scenes. This article explores route panorama projection, resolution, and shape distortion. It also discusses how to improve quality, achieve real-time transmission, and display long route panoramas on the Internet. I n ancient western art, compositions showed the perspective of a scene's projection toward a 2D view plane. In

A typical and famous example is a long painting scroll named A Cathay City (see Figure 1 ), painted 900 years ago. It recorded the prosperity of the capital city of ancient China in the Song Dynasty by drawing scenes and events along a route from a suburb to the inner city. The invention of paper in ancient China allowed most paintings to be created on foldable and scrollable papers instead of canvases. As opposed to a single-focus perspective projection at one end of a street or a bird's eye view, one benefit of this scrollable style is that a pathoriented projection can display more detailed visual information in an extended visual field than a single-focus perspective projection at one end of a street or a bird's-eye view from the top. Today we can realize a composition approach similar to A Cathay City by creating a new image medium-Route Panorama, a program that contains an entire scene sequence along a route. We generate long route panoramas by using digital image-processing techniques and render route views continuously on the Internet. Now we can capture, register, and display route panoramas for many miles taken from vehicles, trains, or ships. We can use this approach for many practical purposes, including profiles of cities for visitors or for introductory indexes of local hometowns. In an extended manner, we could probably even use it as part of something like an enhanced version of Mapquest for people navigating through large cities like Los Angeles or Beijing. Figure 2 (next page) shows an example of a route panorama from a one-hour video in Venice, a place where people often get lost. Route scenes on the Internet There are many things to consider when creating a quality route panorama. To begin with, we create a route panorama by scanning scenes continuously with a virtual slit in the camera frame to form image memories. We call it a virtual slit because it isn't an actual lens cover with a slit in it; rather, for each camera image in the video sequence, we're copying a vertical pixel line at a fixed position. We paste these consecutive slit views (or image memories) together to form a long, seamless 2D image belt. We can then transmit the 2D Figure 1.

2019 arXiv   pre-print
Contrary to the usual assumption of at least partial control of quantum dynamics, a surprising recent result proved that an arbitrary quantum state can be probabilistically reset to a state in the past by having it interact with probing systems in a consistent, but uncontrolled way. We present a photonic implementation to achieve this resetting process, experimentally verifying that a state can be probabilistically reset to its past with a fidelity of 0.870±0.012. We further demonstrate the

Drawing Tower In-Line Fabrication and the Spectrum Analysis of Sampled Fiber Grating

Yu Zheng, Wenjing Gao, Haihu Yu, Huiyong Guo, Shan Jiang, Desheng Jiang
2019 Photonic Sensors  
Sampled fiber grating is a special superstructure fiber Bragg grating with a wide range of applications in many fields. In this work, based on drawing tower in-line fabrication system, a new preparation method of the sampled fiber grating is proposed and experimentally demonstrated. Experimental result shows that the obtained sampled fiber gratings possess dense reflection spectra, with a minimum reflection peak interval of only 0.09 nm. This method exhibits promising application prospect in

On the other hand, the spectral characteristics of the sampled fiber grating are analyzed when the sub-grating is affected by the external physical quantities such as, in this paper, strain. Wavelength shift and intensity change in the reflection peak of the spectra indicate that the grating is affected differently by micro strains, due to the different spatial positions along the axis of the sampled fiber grating. This work is aimed at exploring the potential applications of the sampled fiber grating in quasi-distributed micro-area sensing with the millimeter level.

2022 Drones  
Unmanned aerial vehicles (UAVs) have been widely used for target detection in modern battlefields. From the viewpoint of the opponents, false target jamming is an effective approach to decrease the UAV detection ability or probability, but currently there are few research efforts devoted to this adversarial problem. This paper formulates an optimization problem of false target jamming based on a counterpart problem of UAV detection, where each false target jamming solution is evaluated

To efficiently solve the problem, we propose an evolutionary framework, which is implemented with four popular evolutionary algorithms by designing/adapting their evolutionary operators for false target jamming solutions. Experimental results on 12 test instances with different search regions and numbers of UAVs and false targets demonstrate that the proposed approach can significantly reduce the UAV detection probability, and the water wave optimization (WWO) metaheuristic exhibits the best overall performance among the four evolutionary algorithms. To our knowledge, this is the first study on the optimization of false target jamming against UAV detection, and the proposed framework can be extended to more countermeasures against UAV operations.

Nonparametric Topic Modeling with Neural Inference [article]

Xuefei Ning, Yin Zheng, Zhuxi Jiang, Yu Wang, Huazhong Yang, Junzhou Huang
2018 arXiv   pre-print
This work focuses on combining nonparametric topic models with Auto-Encoding Variational Bayes (AEVB). Specifically, we first propose iTM-VAE, where the topics are treated as trainable parameters and the document-specific topic proportions are obtained by a stick-breaking construction. The inference of iTM-VAE is modeled by neural networks such that it can be computed in a simple feed-forward manner. We also describe how to introduce a hyper-prior into iTM-VAE so as to model the uncertainty of

Moreover, we also propose HiTM-VAE, where the document-specific topic distributions are generated in a hierarchical manner. HiTM-VAE is even more flexible and can generate topic distributions with better variability. Experimental results on 20News and Reuters RCV1-V2 datasets show that the proposed models outperform the state-of-the-art baselines significantly. The advantages of the hyper-prior technique and the hierarchical model construction are also confirmed by experiments.

New Selection Rules from Angular Momentum Conservation [article]

Minyuan Jiang, Jing Shu, Ming-Lei Xiao, Yu-Hui Zheng
2020 arXiv   pre-print
We derive the generalized partial wave expansion for M → N scattering amplitude in terms of spinor helicity variables. The basis amplitudes of the expansion with definite angular momentum j consist of the Poincare Clebsch-Gordan coefficients, while j constrains the UV physics that could generate the corresponding operators at tree level. Moreover, we obtain a series of selection rules that restrict the anomalous dimension matrix of effective operators and the way how effective operators contribute to some 2 → N amplitudes at the loop level.

Attentive Geo-Social Group Recommendation [article]

Fei Yu, Feiyi Fan, Shouxu Jiang, Kaiping Zheng
2019 arXiv   pre-print
Social activities play an important role in people's daily life since they interact. For recommendations based on social activities, it is vital to have not only the activity information but also individuals' social relations. Thanks to the geo-social networks and widespread use of location-aware mobile devices, massive geo-social data is now readily available for exploitation by the recommendation system. In this paper, a novel group recommendation method, called attentive geo-social group
more » ... mmendation, is proposed to recommend the target user with both activity locations and a group of users that may join the activities. We present an attention mechanism to model the influence of the target user u_T in candidate user groups that satisfy the social constraints. It helps to retrieve the optimal user group and activity topic candidates, as well as explains the group decision-making process. Once the user group and topics are retrieved, a novel efficient spatial query algorithm SPA-DF is employed to determine the activity location under the constraints of the given user group and activity topic candidates. The proposed method is evaluated in real-world datasets and the experimental results show that the proposed model significantly outperforms baseline methods.
