Unknown object recognition and description

When we humans see an unknown object, we can recognize it as some kind of object even if we don't know what it is. We also describe the relationship with other objects, e.g., an unknown object is on the table and besides the laptop.

On the other hand, robots can only detect objects that their object detectors have learned about and cannot estimate the relationship with other objects. Our team is researching the topic, "object recognition including unknown objects and relationship estimation".

The recognition problem including unknown objects is called the open-set recognition problem, which has recently attracted much attention in the computer vision field. On the other hand, the problem of recognizing relations among objects and describing them in a graph structure is called scene graph generation (SGG). Our team has named the problem of describing a scene containing unknown objects in a graph structure as open-set scene graph generation (Open-set SGG).

We have formulated the problem setup, proposed experimental protocols and evaluation metrics, and proposed a baseline method of the problem.

Human pose prediction from short time observations

Observing a person's activities and predicting the person's current state and future pose a few seconds later are important for many applications, such as proactive support by robots. Our team is working on predicting a person's future poses by observing the short-term behavior of the person.

Recent development in pose estimation techniques has led to many studies on human behavior using a sequence of human skeletons. Sequences of human skeletons are often considered a graph; vertices have locations of body joints, and edges represent the connectivity of body joints. Thus, graph-convolution-based methods have been proposed. However, some of the body motions cannot be distinguished only from the skeleton sequence in the future pose estimation task. In our study, we have proposed a method to predict future motions by using additional information, such as human surroundings.
