Image registration plays an important role in many practical problems in diverse fields such as medical, remote sensing, and computer vision. The basic purpose of image registration is to obtain the finest geometrical and radio-metrically aligned image from temporal or multi-modal image sensors. In this paper, a novel stable shape feature-based image registration method has been proposed by matching...
To further improve the definition and contrast of remote sensing images, a method of remote sensing image enhancement in non-subsampled shearlet transform (NSST) domain is proposed based on multi-stages particle swarm optimization (MSPSO) algorithm and fuzzy sets. Firstly, the image to be enhanced is decomposed into a low-frequency sub-band and several high-frequency sub-bands through NSST. Secondly,...
The relative radiometric calibration is essential to get high-quality remote sensing images. An efficient way to bypass the quest of uniformity is to use the satellite agility in order to align the ground projection of the scanline on the ground velocity. This weird viewing principle(side-slither) allows all the detectors to view the same landscape. A relative radiometric calibration model based on...
