Idem

https://idem.vision/
Powered by machine learning technology, Idem is an intelligent tool that rapidly scans the web and finds uses of your original copyrighted images and videos, even matching doctored or edited versions.

GagoUI

https://github.com/vahagnIV/gago-ui
A small visual tool written in C++ to easily calibrate a stereo camera rig. It requires installing LibGago, a separate library (also written by me) that provides functionality for reading from and synchronizing two cameras. The existing tools provided with OpenCV and MATLAB are command-line and require some manual work.

Reimplementation of ORB SLAM3

https://github.com/vahagnIV/orb_slam3
A library for simultaneous localization and mapping (SLAM) for autonomous systems such as robots. This is a reimplementation of ORB SLAM3 library by Carlos Campos, Richard Elvira, Juan J. Gómez Rodríguez, José M. M. Montiel, and Juan D. Tardos.
