Abstract Person Re-identification (re-ID) is a hot research topic in the field of
computer vision now, which can be regarded as a sub-problem of image retrieval.
The goal of person re-ID is to give a monitoring pedestrian image and retrieve
other images of the pedestrian across the device. At present, person re-ID is mainly
divided into two categories. One is the traditional methods, which relies heavily
on manual features. The other is to use deep learning technology to solve. Because
traditional methods mainly rely on manual feature, they cannot adapt well to a
complex environment with a large amount of data.… More >

Abstract Cultivated land extraction is essential for sustainable development and
agriculture. In this paper, the network we propose is based on the encoderdecoder structure, which extracts the semantic segmentation neural network of
cultivated land from satellite images and uses it for agricultural automation
solutions. The encoder consists of two part: the first is the modified Xception, it
can used as the feature extraction network, and the second is the atrous
convolution, it can used to expand the receptive field and the context information
to extract richer feature information. The decoder part uses the conventional
upsampling operation to restore the original resolution.… More >

Abstract Modern autonomous vehicles are getting progressively popular and
increasingly getting closer to the core of future development in transportation
field. However, there is no reliable authentication mechanism for the unmanned
vehicle communication system, this phenomenon draws attention about the
security of autonomous vehicles of people in all aspects. Physical Unclonable
Function (PUF) circuits is light-weight, and it can product unique and
unpredictable digital signature utilizing the manufacturing variations occur in
each die and these exact silicon features cannot be recreated theoretically.
Considering security issues of communication between Electronic Control Units
(ECUs) in vehicles, we propose a novel delay-based PUF circuit… More >

Abstract In order to improve the accuracy of wireless network positioning, the
triangulation method of wireless network positioning technology is proposed,
which is based on the linear least square fitting method. It makes the observed
value and the fitting value very close, effectively solves the problem of
significant contradiction between the fitting result and the observed value in the
principle of least square method, and can realize the accurate measurement of
geographic information by wireless network positioning technology. More >
