Levon Khachatryan

I am a senior machine learning researcher specializing in computer vision, with expertise in generative modeling, segmentation and classical computer vision. Currently driving innovation at Picsart, where I contribute to groundbreaking projects in image and video domains. Additionally, I share my knowledge and expertise as a Computer Vision Lecturer in the Applied Statistics and Data Science (ASDS) Master’s program at YSU , while also supervising master’s theses for students.

My research interest lies in computer vision:

Image / Video Segmentation
Image / Video Generation
Image / Video Editing
