Radiometric framework for image mosaicking [PDF]

open access: yesJournal of the Optical Society of America A, 2005
Nonuniform exposures often affect imaging systems, e.g., owing to vignetting. Moreover, the sensor's radiometric response may be nonlinear. These characteristics hinder photometric measurements. They are particularly annoying in image mosaicking, in which images are stitched to enhance the field of view.

In-Focus Imaging by Mosaicking and Super-Resolution [PDF]

open access: yes2006 International Conference on Image Processing, 2006
Although an all-in-focus image can be generated by mosaicking all the best focused regions of a sequence of acquired images taken under different focal settings, an even better-resolved result can be obtained with those discarded less-focused regions which actually contain more useful information.

Fast UAV Image Mosaicking by a Triangulated Irregular Network of Bucketed Tiepoints

open access: yesRemote Sensing, 2023
To take full advantage of rapidly deployable unmanned aerial vehicles (UAVs), it is essential to effectively compose many UAV images into one observation image over a region of interest.

Learning-based keypoint registration for fetoscopic mosaicking. [PDF]

open access: yesInt J Comput Assist Radiol Surg, 2023
Abstract Purpose In twin-to-twin transfusion syndrome (TTTS), abnormal vascular anastomoses in the monochorionic placenta can produce uneven blood flow between the two fetuses. In the current practice, TTTS is treated surgically by closing abnormal anastomoses using laser ablation.
