Julien in a few words

Fraichement diplôme d'un master Informatique Graphique et Analyse d'Images, je me lance en Freelance. J'ai une année d'expérience en vision par ordinateur. Où j'ai entrainer un modèle Mask-RCNN pour les défauts de surface. J'ai une petite expérience en recherche dans la vision par ordinateur toujours, où je vais détecter et reconnaitre des objets 3D dans des nuages de points générée par un LiDar. J'ai toujours été passionné d'informatique. La programmation est quelque chose qui fait partie de mes hobbies. J'ai fait beaucoup de hackathon pour ces même raisons.

September 2019 - Today

1st project: Adaptation of MaskRCNN for surface defects segmentation then adaptation for everything (generic code with only few parameters). I did the whole training and added an evaluation tool. I also added some metrics such as instance callback, and k fold cross validation to ease the training. I'm currently at 0.85 precision and 0.76 recall with a 800 images dataset. We are aiming for 0.90. I also developed a server flask (web platform without interface) to communicate with the android app. The android application is made from scratch, it just sends a picture from your device to the server, and the server sends back the results of the NN. But the app is user friendly, there's a lot of side tools such as gallery and sharing. 2nd project: Implementing a software for automatic electric diagram understanding. -Implementation of line tracker -Basic image processing to cleanse the image (filters, binarisation, skeleton ...) -Text detection and recognition by using Tesseract -Training of MaskRCNN to detect the region of interest -Training of MaskRCNN to detect arrows (Python/OpenCV/PyTesseract/Keras)
