The lab works on images and video using signal processing and deep learning.

AboutAbout the lab
Handling images and video with signal processing and deep learning.
The Yoshida Lab studies the fundamental theory of signal processing and applications to images and video built on it.
The lab also works on applying signal processing, optimization theory, and deep learning to multimedia signals such as audio, acoustics, images, video, and text.
It puts particular emphasis on image compression technologies such as JPEG, image and video processing, and computer vision.
Students in Class II of the School of Informatics and Engineering are the main ones who can request assignment to the lab.
Key terms
- Signal processing
- The field of techniques for processing and analyzing signals such as audio and images using mathematical methods.
- Deep learning
- A machine learning method that uses multilayer neural networks to learn features from large amounts of data.
- Super-resolution
- A technique for generating a higher-resolution image from a low-resolution one, aiming for natural and sharp results.
