Ann (Anrong) Peng, Ph.D.


Title: Patent Engineer

Location: Silicon Valley


Dr. Peng assists with prosecuting foreign and domestic patents in the fields of computer vision, machine learning, pattern recognition, image processing and data analysis.  Dr. Peng has extensive research and development experience in the computer vision, machine learning, pattern recognition and image processing areas. Prior to joining Osha Liang, Dr. Peng worked as research scientist and senior staff software engineer in Geometrix, KLA-Tencor, and BD Biosciences in Silicon Valley. She worked on DARPA projects on virtual reality, 3D scene reconstruction from 2D video, texture mapping on 3D graphics models, etc. Dr. Peng also worked on various industry applications, such as wafer inspection, DNA array reading, security camera imaging, real time printing press color alignment, etc. Her Ph.D. thesis dealt with image segmentation using statistical methods.
