Xin Liu

I am a PhD and applied scientist in Computer Vision, Deep Learning, and Computer Graphics. I have been working in these fields since 2004 when I was a student with 8 years of experiences as an applied scientist in industry. I am familiar with c++, python, Caffe, Pytorch, TensorFlow, OpenCV, OpenGL, etc. I am looking for my next job in these fields in Greater Toronto Area.
