Ikenaga Lab
Machine-translated · View original
A lab researching video information systems that compress and recognize video.
AboutAbout the lab
Building video-processing systems, from algorithm to implementation
The Ikenaga Lab studies information systems that handle images and video.
It envisions a society where people can use information anytime, anywhere, with security and comfort, and aims to build the video information systems that are key to that society.
Video compression and video filtering and recognition are its two main pillars.
The lab does not stop at devising algorithms; it carries them through to real-time embedded systems and LSIs.
Key terms
- Video compression
- Technology that reduces the amount of video data, for example by sending only the differences from the previous frame
- LSI
- Large-scale integration: an integrated circuit that puts many circuits on a single chip. It can perform fixed processing quickly and with low power
- Super-resolution
- Processing that fills in fine detail from a coarse image to produce a high-resolution image
ResearchResearch themes
Looking toward the next-generation ubiquitous and ambient information society, the Ikenaga Lab takes as its theme building the various image and video information systems that are key to realizing it. It carries out broad research and development, from the key algorithms to system design.
*Illustrative imageVideo Compression Systems
The lab works on video compression for Super Hi-Vision based on H.265/HEVC, the next-generation image compression standard, and on video transcoders for next-generation video conferencing systems.
*Illustrative imageVideo Filtering and Recognition Systems
Topics include cloud-based video search and recognition systems, super-resolution and HDR filters for ultra-high-definition displays, and object tracking and feature extraction for sports scene analysis and surveillance cameras.
