People of the Sigmedia Group

Current Members

Anil Kokaram

Anil Kokaram received the Ph.D. degree from Cambridge University, U.K., in 1993. Then, he was a Research Fellow with the Cambridge University Engineering Department and Churchill College Cambridge. In 1998, he established the Sigmedia Group ( at Trinity College Dublin. In 2011 a company he founded, Green Parrot Pictures, operating in the consumer image processing space, was acquired by Google. He is currently working as a Tech. Lead in the Chrome Media Group at Google, Mountain View CA. He continues to hold his Professorship with the Department of Electronic Engineering, Trinity College Dublin and is a Fellow of the College. He is the author of over 100 refereed papers in various conferences and journals over the years. His research interests include the general area of digital video processing and algorithms for stereoscopic quality improvement and video processing in the life sciences. He is best known for his work in automated motion picture restoration.

Prof. Kokaram was an Associate Editor of IEEE Transactions in Image Processing from 2002 to 2007. He was a recipient of an Academy Award alongside colleagues at The Foundry (a visual effects software manufacturer in London) for his contribution to a range of visual algorithms in 2007. These are now widely used in the industry for motion-based effects and quality improvement (The Matrix, The Lord of the Rings, King Kong, etc.).

Dr. Naomi Harte

Dr. Naomi Harte is a lecturer in the School of Engineering. She was appointed as an SFI Engineering Initiative Lecturer in Digital Media in 2008. Prior to returning to academia, Dr. Harte worked in high-tech start-ups in the field of DSP Systems Development, including her own company founded in 2002. She also previously worked in McMaster University in Canada. Dr. Harte’s specialist area is Human Speech Communication. Her industrial background brings a real-world approach to her research. Her work involves the design and application of mathematical algorithms to enhance or augment speech communication between humans and technology. Since her appointment, she has established a strong international reputation in the speech processing community. Current projects focus on speech quality, audio-visual speech recognition, emotion in speech, speaker verification and bird species analysis.

David Corrigan

Dr. David Corrigan completed his PhD under Dr. Anil Kokaram in 2008. The thesis was concerned with the effect of motion estimation failure on the robustness of image processing applications, especially with regard to digital film restoration applications. His other research interests include video object segmentation and image texture synthesis. He has also completed a 9 months Marie-Curie post-doc at The Foundry, and is now a research fellow with sigmedia.
