CNNEDGEPOT: CNN based edge detection of 2D near surface potential field data

Original Research Article
Pages 1-8
D. Aydogan

Highlights

► Edge detection plays an important role in the image processing. ► Cellular neural network was proposed for the extraction of sources and edges. ► A MATLAB code was prepared. ► It was implemented on the potential field data.

A graphical user interface application for evaluation of the gravitational tensor components generated by a level ellipsoid of revolution

Original Research Article
Pages 77-83
Michal Šprlák

Highlights

► We offer a software application for evaluation of the normal gravitational tensor. ► Several computational modes and an easy-to-use GUI have been developed. ► The software is convenient for satellite gravitational gradiometry applications.
