About
Hello world! I am working as an Assistant Professor at the department of Computer Science and Engineering of IIIT Guwahati. Prior to that, I was working as an Assistant Professor at IIIT Kota. I received my PhD degree from the department of CSE, Indian Institute of Technology Guwahati in 2016. My doctoral research area was robust watermarking of scalable video sequences. Recently we started working on the problem of text detection in natural images and other computer vision applications
