Co-registering the Sentinel-1 Synthetic Aperture Radar (SAR) and Sentinel-2 optical data of European Space Agency (ESA) is great importance for many remote sensing applications. However, we find that there are evident misregistration shifts between SAR images directly downloaded from official website. To address that, this paper presents a fast effective registration method two types images. In...

mutual information (mi) is a widely used similarity metric for multimodality image registration. however, it involves an extremely high computational time especially when it is applied to volume images. moreover, its robustness is affected by existence of local maxima. the multi-resolution pyramid approaches have been proposed to speed up the registration process and increase the accuracy of th...

to perform an accurate approach to the spine specially for fracture stabilization a 3d model of spine surgical region may improve this mechanism and it can help the surgeon to have a deeper glance to this scenario. the pre-op planning facility is another advantage of the patient spine specific model to take a chance of making guides to direct pedicle screws safely and increase the pathomechanic...

Mouse lung models facilitate the study of the pathogenesis of various pulmonary diseases such as infections and inflammatory diseases. The co-registration of ex vivo histological data and pre-excised magnetic resonance imaging (MRI) in preclinical mouse models would allow for determination and validation of imaging signatures for different pathobiologies within the lung. While slice-based co-re...

Multi-modality microscopes incorporate multiple microscopy techniques into one module, imaging through a common objective lens. Simultaneous or consecutive image acquisition of a single specimen, using multiple techniques, increases the amount of measurable information available. In order to benefit from each modality, it is necessary to accurately co-register data sets. Intrinsic differences i...
