Yamaguchi Lab
Machine-translated · View original
A lab that uses light and image processing technology to display color, texture, and three-dimensional images.
AboutAbout the lab
Reproducing both color and 3D from information in light.
The Yamaguchi Lab builds on light and image processing technology to study spectral imaging, color reproduction, medical imaging, holography, and more.
Its themes are imaging systems that faithfully reproduce the color and texture of real objects, and image analysis technology for quantitative pathological diagnosis.
The lab is also advancing research on 3D displays that use holography to project three-dimensional images into space.
The lab is run jointly by Professor Yamaguchi and Assistant Professor Takeyama.
Key terms
- Multispectral image
- An image that records light split into many wavelengths (colors). It holds finer color information than the three colors of red, green, and blue.
- Holography
- A technique that records the light waves coming from an object and reproduces them to create a three-dimensional image.
- Pathological diagnosis
- Diagnosis in which tissue taken from the body is examined under a microscope to determine whether it is benign or malignant, how far it has progressed, and so on.

ResearchResearch themes
Building on light and image processing technology, the lab studies spectral imaging, hyperspectral imaging, color reproduction, multi-primary displays, medical imaging, three-dimensional imaging, holography, and more. It works on imaging technology that reproduces the color, texture, and three-dimensional appearance of real objects, and on pathological image analysis technology.
*Illustrative imageImaging That Reproduces the Color and Texture of Real Objects
The lab develops imaging technology based not only on the three primary colors of red, green, and blue but also on “multispectral” and “multi-primary” approaches. The aim is to reproduce the color and texture of real objects faithfully, with a high degree of realism.
*Illustrative imageEstimating High-Resolution Spectral Images from Few Observations
This research estimates multispectral and hyperspectral images, which carry fine wavelength information, at high resolution from limited observations. The lab also aims for one-shot imaging, which captures an image in a single exposure, and for video capture.
*Illustrative imageImage Analysis for Quantitative Pathological Diagnosis
The lab applies pattern analysis techniques to digital pathology images, aiming at quantitative and highly accurate pathological diagnosis. It works on deep-learning techniques that recognize the structure of cells and tissue, and on color correction techniques for pathology images.
*Illustrative image3D Displays Using Holography
This research displays three-dimensional images using holography. The lab works on holographic 3D printers, computational holography, and user interfaces for “touching 3D images.”
