Lab Introduction

The laboratory was set up in the Electrical, Electronics and Information Engineering of Nagaoka University of Technology. The laboratory is now dealing with image and video related signal processing technologies. Our research oriented topics include lifting wavelet transform, integer orthogonal transform, lossless and lossy image compression, high dynamic range image processing, etc. The laboratory has some projects with some companies and universities for development of robot vision, bio-related signal processing and video sensing technologies.
