Main research

Video Analysis for Safety and Security

In recent years, a great number of cameras have been operated. To use these cameras effectively, it is important to reduce the burden of watchmen by video analysis and to protect the privacy of people in video scene. In this research project, we work on video analysis and its hardware acceleration to realize a safe and secure social environment.

Identification Technologies for Digital Cameras Using Image Sensor’s Noise

It is known that DNA and finger print are useful for identifying a human. A camera also has unique noise and it is included in an image taken by the camera though it is very small. By using the unique noise, we can know which camera took an image and which part was falsified in an image. In this research project, we aim to realize methods to extract the unique noise precisely in an image and their applications.
