Chaos Lab
Machine-translated · View original
A lab centered on chaos and image compression that also extends to supporting content creation.
AboutAbout the lab
From chaos and image compression to creative support.
The Chaos Lab studies nonlinear problems with few degrees of freedom, centered on chaos, fractals, and bifurcation theory.
Image compression and decompression are central to the lab's development of core technologies for computer amusement.
The lab also works on technology for automatically generating 2D animation, which supports the creation of content made by users.
Prof. Tokunaga's page also introduces products in which image compression technology, developed jointly with companies, was built into game software and other items.
Key terms
- Chaos
- A phenomenon in which a system that follows simple rules nonetheless shows irregular behavior whose future state is hard to predict
- Fractal
- A figure or structure in which the whole and its parts repeat similar shapes
- UGC
- Short for User Generated Content; content created by users themselves
ResearchResearch themes
The lab's research themes are nonlinear problems centered on chaos, fractals, and bifurcation theory, and technology development for computer amusement centered on image compression. The achievements listed on the website are up to around 2014.
*Illustrative imageChaos, Fractals, and Bifurcation Theory
Centered on chaos, fractals, and bifurcation theory, the lab studies nonlinear problems that can be described with few degrees of freedom.
*Illustrative imageImage Compression and Decompression Technology
Centered on image compression and decompression, the lab develops core technologies for computer amusement. These were commercialized jointly with companies and built into game software and image-processing LSIs for pachinko and pachislot machines.
*Illustrative imageUGC Creation Support and Automatic 2D Animation Generation
Centered on the automatic generation of 2D animation, the lab develops technologies that support the creation of UGC (user-generated content).
