Digital image watermarking is one of the effective schemes to protect copyrights still images. However, existing are not robust enough common geometric transformation attacks such as arbitrary rotation, scaling and shifting with desirable hiding capacity. To address this issue, we propose a scheme based on correction codes (GCCs). In scheme, watermark pre-set GCCs combined embedded into cover o...

This paper established strict image-object relationship model of ZY-3,and analyzed orbital data and attitude data statistically. It did camera geometric calibration using high-precision artificial target. Internal geometric correction of the original satellite images, eliminating the interior orientation parameters such as non-uniform transition, transition of the integration time and attitude ...

This paper describes how geometric distortion correction and image processing operation can be performed in realtime on an IVIP system. The IVIP is a modified version of RVIP RVIP is currently being manufactured and it is going to be used for radar signal processing. The IVP is targeted to perform the time consuming first stages of image processing. This includes geometric distortion correction...

This paper briefly describes the methods available for collection, atmospheric and geometric correction, and processing of hyperspectral imagery. Discussion of data capture concentrates on logistics of integrating image acquisition with field data collection. Atmospheric correction is required to use the imagery with reference spectra from field and laboratory sensors; a variety of methods for ...

This paper describes the application of refined plate theory to investigate free vibration and buckling analyses of functionally graded nanocomposite plates reinforced by aggregated carbon nanotube (CNT). The refined shear deformation plate theory (RSDT) uses four independent unknowns and accounts for a quadratic variation of the transverse shear strains across the thickness, satisfying the zer...

In this paper, a refined plate theory is applied to investigate the free vibration analysis of functionally graded nanocomposite sandwich plates reinforced by randomly oriented straight carbon nanotube (CNT). The refined shear deformation plate theory (RSDT) uses only four independent unknowns and accounts for a quadratic variation of the transverse shear strains across the thickness, and satis...
