The classification accuracy of underwater image, which have the special image characteristic, is lower than the corresponding result of images in the air. A study was carried out to underwater image classification with deep convolutional neural networks and the classification ability was improved with two data augmentation methods. The experiments showed that the submarine image classification with...
Recently, 60 GHz technology has become a promising alternative for indoor positioning systems because it can provide very accurate temporal and spatial information for precise time of arrival (TOA) estimation. However, non-line-of-sight (NLOS) propagation in indoor environments can significantly degrade the localization accuracy with 60 GHz signals. To reduce the effects of NLOS propagation, a fingerprinting...
In this paper, two new methods: ECA and 2DECA are proposed for face recognition, which are inspired by KECA. In ECA (2DECA), features are selected in PCA (2DPCA) subspace based on the Renyi entropy contribution instead of cumulative variance contribution. Then the proposed methods are tested on the OLR, YALE and XM2VTS databases respectively. We also compare the performance of the related methods...
In this era of information system using traditional library information systems may waste time and resources, and might cause mistakes in work flow. In order to solve these problems, in this paper we have shown the usages of the Library Information Systems based on Three Layers Architecture. This model is composed of Presentation Layer, Business Logic Layer and Data Access layer. In this model we...
