h-index = 15 (June 2020)

I am author of so many impactful scientific journals and books.

I have been contributing to the literature with novel and robust mathematical methods, algorithm design and implementations. My main focus is to make the computers analyse and understand images, detect objects almost like human can see and understand them. Developing algorithms robust to the viewing conditions and sensor parameters is where I feel so much enthusiastic about. This is why lately I became highly engaged with Deep Learning algorithms.

Coming from computer vision field, I applied my knowledge on remote sensing data (satellite/drone images), but I have been also working on indoor navigation problems of computer vision (visual odometry, SLAM).

As an artist, I love rendering the results in 2D/3D and even as AR/VR applications for easy interaction with the users.
