In the Laboratory for Image and Media Understanding (LIMU), our goal is to establish a novel framework to (1) retrieve social information from observation data obtained with various sensors and (2) to create innovative content for the society by analyzing those data. While developing the tools necessary to build such a framework, we carefully design the algorithms such that anybody in the society can later interact with such a cyber–physical world to improve analysis performances and users experience. To this end, the research in the lab is focused around two main axis: Computer Vision (CV) and Cyber-Physical System (CPS). The goal of Computer Vision is to make the computer “see” the world. This means to develop techniques to analyze, recognize and process visual information such as images and videos. Among other problematics of CV, one important topic is how to accurately measure and recognize 3D shapes and their motions for efficient scene understanding. This can be done by using multi-view cameras or depth cameras. 2.5D data captured by such cameras can be combined to create useful 3D content. In the lab, captured visual data are used for application in the agricultural world. Results of our analysis on plant growth, vegetable production and harvesting are provided to our farmer collaborators with various information that help for everyday support and production improvement. In this research (which is a part of the CPS project), we are making much efforts to establish the next-generation agricultural Internet of Things (IoT). Various sensors are installed in farms and captured data are analyzed using most recent machine learning technologies. On the other hand, research is also conducted to analyze data from wireless sensors and web systems. Various data collected on the Itoshima campus are analyzed to predict social events and crowd movements. These results can be used to develop services leading to a more efficient and sophisticated society.

Pattern recognition is a research field that focuses on the artificial realization of the human cognitive system. It is still difficult even though computers are highly developed today. For example, we humans can easily recognize a car at a glance as “That is a car.” However, there are numerous models in cars, and appearance will change depending on a point of view even if we look at the same model. The easiest way to handle this issue is to classify the input based on the similarity to patterns stored in a computer in advance, but challenges remain such as the definition of similarity. The key point is how to handle variety in patterns that causes difficulty. In this laboratory, we develop pattern recognition techniques and the related applications such as image processing/recognition, bioimage informatics, machine learning, and character engineering/science. We are challenging these attractive problems with our unique techniques and competing against the world.

ICT (Information Communication Technologies) are more required in our lives. We are developing technologies in three directions to tackle the problems in our daily lives and in social lives.

  1. Fundamental technologies: We are developing low cost sensing technologies such as acoustic vehicle sensing system for better understanding of the world around us. We are also working on wireless communication technologies to collect sensing data from small IoT devices.
  2. Software development technologies: Embedded systems including small sensors and automobiles have no output devices, which put difficulties in software development, especially on debugging. We are developing DSLs (domain specific languages) that drastically reduce development costs. We are also developing DSLs that give us rich information such as power consumption for better software development.
  3. Reverse Innovation: ICT became the core component to serve social services (healthcare, education, business) in developing countries. We are developing social needs-based solutions that can directly serve the society e.g. remote healthcare system to reduce healthcare cost, new car sharing model that can increase social impact. We examine our concept in developing countries and plan to use the same technology in developed countries as well.

We aim to study human-centered intelligence. To this end, we analyze real data under real situations and develop mechanisms to estimate, extract, or acquire information users want and provide it to them when they need, considering their contexts, intentions, preferences, interests, and privacy issues. For example, to share and leverage information to help user mobility, we are developing an information sharing and leveraging platform for smart mobility called Ito Campus Life: https://ito.ait.kyushu-u.ac.jp/itocamlife/, and a platform to record, reuse and leverage information about people’s communication situations recognized in real world, called Real SNS. To capture and predict road congestions at some specific area, we conduct mining of time-series location data such as vehicle probe data. We also conduct mining of open data provided by municipalities to find and leverage information to enrich civil life and to take away concerns and troubles on everyday life. Further, collecting and analyzing student comments about their learning written after every lesson, we develop methods to estimate their learning situations or performance and build mechanisms to give feedback to them to improve their learning motivations and activities.
