Education : Ph.D. (Nanyang Technological University Singapore)

Dr. Viswanath Gopalakrishnan  finished his B.Tech from National Institute of Technology, Calicut and received Ph.D. from School of Computer Engineering, Nanyang Technological University, Singapore  in 2011. 

His Ph.D. topic was focused on building computational models for identifying salient  regions in images and videos. From 2011 - 2019 he worked with Samsung Research Institute, Bangalore on various research topics of interest  in the areas Computer Vision and Machine Learning. During this period he was involved in developing and leading the efforts  towards machine learning based vision algorithms for  Samsung's flagship models which involved Object Detection, Scene Recognition, Semantic Role Recognition and Object & Scene Segmentation. His current research areas of interest  are  in Vision + Language multimodal fusion, Self Supervision / Few-Shot learning techniques for image/video segmentation.
