Co-registration and complex interpolation

چکیده
SAR interferometry is a promising and sophisticated technique by which two SAR images of the same scene, acquired from two consecutive passes of the carrying satellite platform, are brought into interference for generating a digital terrain model of the observed surface. Due to the difference in viewing angles and to a non-strict parallelism of the orbits at the times of acquisition, corresponding pixels in the two images are not necessarily associated with the same terrain element, leading to image de-correlation. The pre-requisite for interferometry is therefore that the two images be accurately superimposed to each other, i.e., co-registered.

A Study on Robustness of Various Deformable Image Registration Algorithms on Image Reconstruction Using 4DCT Thoracic Images
Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...
متن کاملImage Quality Degradation and Retrieval Errors Introduced by Registration and Interpolation of Multispectral Digital Images
Full utilization of multispectral data acquired by whiskbroom and pushbroom imagers requires that the individual channels be registered accurately. Poor registration introduces errors which can be signiicant, especially in high contrast areas such as boundaries between regions. We simulate the acquisition of multispectral imagery in order to estimate the errors that are introduced by co-registr...

متن کاملSurface reconstruction of detect contours for medical image registration purpose
Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...
متن کاملReducing Interpolation Artifacts for Mutual Information Based Image Registration
Medical image registration methods which use mutual information as similarity measure have been improved in recent decades. Mutual Information is a basic concept of Information theory which indicates the dependency of two random variables (or two images). In order to evaluate the mutual information of two images their joint probability distribution is required. Several interpolation methods, su...
