We developed an automated technique for non-rigid image registration as a basis for tracking the heart in contrast-enhanced cardiac magnetic resonance (CMR) image sequences. The goal of the present work was to validate this technique against conventional manual analysis. Our approach is based on a multi-scale extension of the normalized 2D cross-correlation algorithm in combination with level-set...
In this paper, taking SPOT5 HRG as an example, multi-parameter interpolation methods is firstly built by analyzing ephemeris data and a rigorous physical geometry imaging model is derived. Taking the case of images in Kunming area, image rectification experiment was then performed using no control point and lack control points. Eventually, the experimental results are analyzed in details.
We describe a methodology that is used for the automatic georeferencing of multispectral images acquired from airborne pushbroom imaging cameras. This methodology is based upon the dense registration of flight strips data onto a reference orthoimage and uses the mutual information criterion to make the raw (source) image and the orthoimage (target) aligned. By taking into account a rigorous modeling...
