Photometric visual servoing

WebThis paper deals with the development of a vision-based controller for robot-assisted medical applications. It concerns the use of shearlet coefficients in case of ultrasounds (US) images as visual signal inputs and the design of the associated interaction matrix. The proposed controller was validated in both simulation and on an experimental test bench … WebMar 31, 2024 · * See the file LICENSE.txt at the root directory of this source

Photometric visual servoing for omnidirectional cameras

WebMay 10, 2024 · To date, most of visual servoing approaches have relied on the geometric features that have to be tracked and matched in the image.
