The CMS pixel detector has been designed for a peak luminosity of 10^34cm-2s-1 and a total dose corresponding to 2 years of LHC operation at a radius of 4 cm from the interaction region. Parts of the ...
Radiation hardness of CMS pixel barrel modules
LHC super LHC CMS tracking pixel silicon radiation hardness
2010/3/15
Pixel detectors are used in the innermost part of the multi purpose experiments at LHC and are therefore exposed to the highest fluences of ionising radiation, which in this part of the detectors cons...
Interpolation Artifacts in Sub-Pixel Image Registration
Image registration interpolation artifacts mutual information
2009/12/23
We consider the problem of registering(aligning) two images to sub-pixel accuracy by optimization
of objective functions constructed from the images' intensity values.We show that some widely use
in...

Results of an experimental campaign that took place in the greater Thessaloniki area were used to investigate temporal and spatial UV variability within an OMI satellite pixel. UV irradiance and aeros...
Image Encryption by Pixel Property Separation
Pixel Property Separation Image Encryption Cryptanalytic Error Avalanche Effect
2009/6/11
Pixels in an image are essentially constituted of two properties, position and colour. Pixel Property Separation, a radically different
approach for Symmetric-key image encryption, separates these pr...
Monitoring of Re-generation Condition for Burnt Forested Wetland in Western Siberia with Sub-pixel Land Cover Characterization

2009/3/17
Recently, the number of forest fires in West Siberian Lowland (WSL) is increasing and they are considered as one of the main driving factors influencing carbon cycling in whole earth. Since many fores...
Proposal for measuring the quantum states of neutrons in the gravitational field with a CCD-based pixel sensor
neutron quantumstate gravitational field CCD
2010/4/12
An experimental setup is proposed for the precise measurement of the quantum states of ultracold neutrons bound in the earth's gravitational field. The experiment utilizes a CCD-based pixel sensor and...
A Pixel-Wise Local Information-Base Background Subtraction Approach
Pixel-Wise Local Information-Base Subtraction Approach
