The lab studies digital filters, image processing, and EEG analysis.

AboutAbout the lab
From digital filters to images and EEG.
The Aikawa Lab studies digital filter design, image processing, EEG analysis, and the development of e-learning systems.
The lab designs digital filters required for high-quality communication and high-precision measurement, applying mathematical techniques such as the Fourier transform and projection onto convex sets.
In image processing, it works on super-resolution technology, detection of paint defects, and quantification of cancer cells.
In EEG, it researches and develops an automatic analysis system that simulates the analysis results of doctors.
Key terms
- Digital filter
- A filter that processes signals, required in areas such as high-quality communication and high-precision measurement. This lab designs optimal ones.
- Projection onto convex sets
- One of the mathematical techniques applied to digital filter design.
- Super-resolution
- One of the image processing techniques. It is one of the subjects of this lab's image processing research.
ResearchResearch themes
This lab works on four areas of research: digital filter design, image processing, EEG, and e-learning. It carries out design and development using mathematical techniques and image and EEG analysis methods.
*Illustrative imageDigital filter design
The lab designs optimal digital filters, as required for high-quality communication and high-precision measurement, by applying mathematical techniques such as the Fourier transform and projection onto convex sets.
*Illustrative imageImage processing
Using image processing techniques that find only the necessary parts of an image, the lab studies super-resolution technology, detection of paint defects, and quantification of cancer cells.
*Illustrative imageAutomatic EEG analysis
The lab researches and develops an automatic analysis system that simulates the analysis results of doctors. It can reduce the burden on doctors and analyze how the brain is currently functioning.
*Illustrative imagee-Learning systems
The lab develops a system that lets instructors add exercise problems on the web and automatically manages learning results. In response to the problem of a declining number of engineers who understand hardware, it also develops educational support tools for engineers.
