- Co-founder & CEOFunimateJan 2014 - Current (12 years 6 months)We are the makers of Funimate app, most creative music & lipsync video community. Funimate is a Top-10 Photo&Video app, used by millions of people to create awesome videos.
- Research LeaderNokiaJan 2011 - Jul 2014 (3 years 7 months)Our team was responsible for Nokia's standardization efforts in audio-visual area specifically on 3GPP-SA4 (codec working group), ITU-T SG16 and ISO-IEC/MPEG. In addition, we were responsible for developing a number of differentiating audio-visual technologies for Nokia's future products. I have been personally responsible for the following: - Nokia's participation to JCT-VC for development of the H.265/HEVC video coding standard - Development and submission of Nokia's Scalable H.265/HEVC codec to JCT-VC CfP - Participation in 3GPP-SA4 for definition of HEVC in 3GPP system standards - Initial research and protoyping of the Cinemagraph lens application, which ended up as part of the Nokia WP8 product lines, starting with Lumia 920. - Publici
- Principal Researcher / Program ManagerNokiaSep 2008 - Dec 2010 (2 years 4 months)My main responsibility was working in a program management role within the Nokia-Cisco-Ericsson industry consortium. The joint proposal of this consortium was selected as one of the proposals where the initial design of H.265/HEVC standard is based upon. I was also responsible in coordinating Nokia internal efforts towards H.265/HEVC and supervised researchers and students. In addition, I worked on establishing collaborations with other companies in 3D video field and publicized Nokia’s research results in various events, such as Nokia World, NRC Hollywood opening, etc.
- Senior ResearcherNokiaSep 2004 - Dec 2008 (4 years 4 months)During my first years at Nokia, I was heavily involved on Nokia’s proprietary H.264/AVC codec mostly working on rate control and error resilience issues. In addition, I worked with several multimedia related Nokia products, focusing on H.264/AVC encoder design. Starting in 2006, I started to contribute to international standardization projects, including many accepted contributions to 3GPP MBMS standardization, MVC extensions of H.264/AVC and ITU-T explorations towards H.265.
- RVideo Software EngineerReality Commerce CorporationJan 2003 - Dec 2004 (2 years)At RCC, I was working on encoder algorithms (rate control and motion estimation) for the company's H.264/AVC encoder product on Equator chipsets.

- IIntra Coding of the HEVC StandardThis paper provides an overview of the intra coding techniques in the High Efficiency Video Coding (HEVC) standard being developed by the Joint Collaborative Team on Video Coding (JCT-VC). The intra coding framework of HEVC follows that of traditional hybrid codecs and is built on spatial sample prediction followed by transform coding and postprocessing steps. Novel features contributing to the increased compression efficiency include a quadtree-based variable block size coding structure, block-size agnostic angular and planar prediction, adaptive pre- and postfiltering, and prediction direction-based transform coefficient scanning. This paper discusses the design principles applied during the development of the new intra coding methods and
- BBlock Merging for Quadtree-Based Partitioning in HEVCThe joint development of the upcoming High Efficiency Video Coding (HEVC) standard by ITU-T Video Coding Experts Group and ISO/IEC Moving Picture Experts Group marks a new step in video compression capability. In technical terms, HEVC is a hybrid video-coding approach using quadtree-based block partitioning together with motion-compensated prediction. Even though a high degree of adaptability is achieved by quadtree-based block partitioning, this approach has certain intrinsic drawbacks, which may result in redundant sets of motion parameters being transmitted. Previous work has shown that those redundancies can effectively be removed by merging the leafs of a particular quadtree structure. Following this concept, a block merging algorithm
- HHigh Performance, Low Complexity Video Coding and the Emerging HEVC StandardThis paper describes a low complexity video codec with high coding efficiency. It was proposed to the high efficiency video coding (HEVC) standardization effort of moving picture experts group and video coding experts group, and has been partially adopted into the initial HEVC test model under consideration design. The proposal utilizes a quadtree-based coding structure with support for macroblocks of size 64 × 64, 32 × 32, and 16 × 16 pixels. Entropy coding is performed using a low complexity variable length coding scheme with improved context adaptation compared to the context adaptive variable length coding design in H.264/AVC. The proposal's interpolation and deblocking filter designs improve coding efficiency, yet have low complexity.
