Image Registration Techniques: A Survey

, 2017
Image Registration is the process of aligning two or more images of the same scene with reference to a particular image. The images are captured from various sensors at different times and at multiple view-points.

Hand–eye calibration using a target registration error model

Healthcare Technology Letters, 2017
Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand–eye calibration between the camera ...

Miniature optical planar camera based on a wide-angle metasurface doublet corrected for monochromatic aberrations

, 2016
Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by enabling complex low-cost systems where multiple metasurfaces are ...

Infrared and Visible Image Fusion Under Different Illumination Conditions Based on Illumination Effective Region Map

IEEE Access, 2019
It is well known that the quality of visible images taken under different illumination conditions varies greatly, so the illumination factors will affect infrared and visible image fusion effects inevitably.
