My name is Natacha Ruchaud. I was born in Gassin, France in 1991. I received my engineer diploma in 2014 in Vision, Image and Multimedia from Polytech Nice-Sophia ( http://www.polytechnice.fr/ ). Currently, I am a PhD Student since 09/2014 at Eurecom ( http://www.eurecom.fr/en ), Sophia Antipolis, France in the Digital Security Departement ( http://www.eurecom.fr/en/research/networking-and-security-department ), under the supervision of Prof. Jean-Luc DUGELAY.

Since I began my studies in Computer Science I have been interested in many domains in Image and Video processing as: Privacy protection, Compression, Biometrics, Object Recognition, Machine Learning, Text detection and recognition (OCR), 3D mesh models, Sensors of Kinect / Drone / Phone.

My thesis consists of protecting the people privacy in the video surveillance. The main goal is to combine the privacy protection while keeping a fair visualization of the events in the scene. Moreover, to be compliant with the usefulness of video monitoring, three other criteria are important: the reversibility, the compression and running in real time.
