Ahmed Sabir

I'm currently a second year PhD student at BarcelonaTech. I did my MSc at the Masuda AI lab at the Kanagawa Institute of Technology under the supervision of Prof. Michiko Matsuda/Hiroshi Tanaka. Now, I'm a member of the TALP Research Group and my advisor is Prof. Lluís Padró.

My previous research was gesture recognition, sign languages and OCR for accessibility application. Especially OCR, and how to make text accessible for blind people. Now, I'm working on text recognition in the wild. Before that, I used to work as measurement specialist to do programming, service maintenance, and testing for reservoir mapping while drilling tools.

I'm interested in Natural Languages Processing, Computer Vision and Machine learning. Especially, the intersection between language, vision and secne understanding. My current research fouces on adding visual context information to enhnace OCR Re-ranking score. Before that, I was working on human pose and semaphore flag signaling recognition system.
