CNN BASED RETINAL IMAGE UPSCALING USING ZERO COMPONENT ANALYSIS
Image upscaling CNN ZCA Whitening Retinal Images
2017/5/15
The aim of the paper is to obtain high quality of image upscaling for noisy images that are typical in medical image processing. A new training scenario for convolutional neural network based image up...
Exploring Semantic Inter-class Relationships (SIR) for Zero-shot Action Recognition
Exploring Semantic Inter-class Relationships Zero-shot Action Recognition
2016/1/22
Automatically recognizing a large number of action cat-egories from videos is of significant importance for video understanding. Most existing works focused on the design of more discriminative featur...
Study on Copyright Authentication of GIS Vector Data Based on Zero-Watermarking
GIS Copyright Authentication Digital Product Vector Data Zero-watermarking Hash
2015/12/18
GIS vector data is closely linked with the development of social economy and national defense, which is of high production cost and high precision, so the copyright protection of GIS vector data means...
REGISTERING INTERFEROMETRIC SAR IMAGES USING MARRHILDRETH ZERO-CROSSINGS
Registration SAR Edge Image Digital
2015/6/1
Leberl (Leberl, 1990) proposed an edge-based algorithm for finding matching pairs of points in SAR images. In this paper, we show that the algorithm can be used to register interferometric SAR images ...

Zero-resource speech processing spoken term discovery speech summarization
2014/11/27
Zero-resource speech processing involves the automatic analysis of a collection of speech data in a completely unsupervised fashion without the benefit of any transcriptions or annotations of the data...
Developing a Social Business Model for Zero Waste Management Systems: A Case Study Analysis
Reuse Recycling Waste Business Extended Producer Responsibility Social Enterprise Social Business
2012/11/12
The global gross domestic product (GDP) has increased by 40% during 1960-2000; poverty and inequity have also increased over the same time [1]. Many social scientists and economists have indicted the ...
H2 Gas Charging of Zero-Valent Iron and TCE Degradation
Granular Zero-Valent Iron Hydrogen TCE Remediation Groundwater
2012/3/11
Granular zero-valent iron (ZVI) has been widely used to construct permeable reactive barriers (PRB) for the in situ remediation of groundwater contaminated with halogenated hydrocarbons. In the anaero...
Hybrid data mining-regression for infrastructure risk assessment based on zero-inflated data
Classification tree Risk assessment Regression Zero-inflated
2011/11/19
Infrastructure disaster risk assessment seeks to estimate the probability of a given customer or area losing service during a disaster, sometimes in conjunction with estimating the duration of each ou...
Impact of chirp on spectral recoil of solitons in a defect-core photonic crystal fiber with two zero-dispersion wavelengths
Pulse propagation temporal solitons Photonic crystal fibers
2011/5/22
Increasing input chirp decelerates (accelerates) the spectral recoiling process across a negative dispersion slope for pulses experiencing normal (anomalous) dispersion. A realistic defect-core photon...
Tolerance to nonlinearity of 40 Gb/s BPSK-based coherent solution over legacy systems based on non-zero dispersion- shifted fibers
coherent communication optical communication
2011/5/22
We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution ag...
Quantum critical coupling conditions for zero single-photon transmission through a coupled atom-resonator-waveguide system
Quantum critical coupling conditions zero single-photon transmission coupled atom-resonator-waveguide system
2010/8/10
The quantum critical coupling conditions, where single-photon transmission goes to zero, for systems of a coupled ring resonator and atom in a one-dimensional single-mode waveguide are discussed. The ...
