Feature-matching based overlay of 7 years of high-resolution imagery collected by the TEMPO ecological module (EMSO-Azores observatory)

Autre

The dataset contains raw screenshots retrieved from video sequences collected by the TEMPO ecological module from 2012 to 2019 at a frequency from infra-daily to 10 days (base of the Eiffel Tower hydrothermal edifice, Lucky Strike, Mid-Atlantic Ridge, depth of 1695m). These screenshots were all transformed in a continuous spatio-temporal image reference system. This homography transformation was calculated by a combination of feature-matching algorithm and manual annotation of keypoints. All homography transformation matrices and images transformed are included. The dataset is accompanied with a read me to describe the structure of each data. Please contact Loïc Van Audennhaege for further information on the workflow.
