The work compares the of sparse image interpolation methods such as: - method sequential computation Fourier spectrum (IMSCS), projections onto convex sets (projections sets, POCS), and amplitude iterations (MAI). All calculations necessary for reconstruction images are performed only on spatial spectra. As an example, aerospace digital is used, which typical tasks remote sensing earth's surfac...

Climate plays a key role in ecosystem services. Understanding microclimate change can be significant help making the right decision for ecosystems and buffering effects of global warming. Given large distances between meteorological stations changes climate variables within short distances, such variations cannot detected just by using observed data. This study aimed at determining spatial stru...

the gravity recovery and climate experiment (grace), twin satellites launched in march 2002, are making detailed measurements of the earth's gravity field. it will yield discoveries about gravity and the earth's natural systems. different sensors and instruments have been placed in the grace satellites to fulfill the primary scientific objective of the mission in mapping the earth’s g...

Interpolation between compatible triangle meshes that represent different poses of some object is a fundamental operation in geometry processing. A common approach is to consider the static input shapes as points in a suitable shape space and then use simple linear interpolation in this space to find an interpolated shape. In this paper, we present a new interpolation technique that is particul...

background: medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. this information may be useful for better diagnosis of possible lesions or better tumor delineation at radiation treatment. to do this, deformable image registration algorithms are mainly utilized to perform image interpolation ...

This thesis includes my three-year doctoral research in the field of image sequence interpolation. The introduced interpolation methods are mainly based on finding an appropriate optical flow field, with which the objects in an initial image can be “transported” and “warped” to a certain time. To identify the optical flow field the interpolation problem is considered in the framework of optimal...
