Lab Director (or Principal Investigator)

Hisakazu Kikuchi received B.E. and M.E. from Niigata University in 1974 and 1976, respectively, and Dr.Eng. from Tokyo Institute of Technology in 1988. From 1976 to 1979 he worked at Information Processing Systems Laboratory, Fujitsu Ltd., Tokyo. Since 1979, he has been with Niigata University, where he is a Professor in the Department of Electrical and Electronic Engineering. He was a visiting scholar in the Electrical Engineering Department, UCLA in 1992. He holds a visiting professorship at Chongqing University of Posts and elecommunications and Nanjing University of Information Science and Technology, both in China, since 2002 and 2005, respectively. His current research interests are in image/video processing for imaging, rendering, printing, compression and analysis.
He is a Fellow of IEICE and a Member of IEEE, ITE, and IIEEJ.
He served the general co-chair of ITC-CSCC 2011 in Korea, the chair of Circuits and Systems Group, IEICE, in 2000 and the general chair of Digital Signal Processing Symposium, IEICE, in 1998 and Karuizawa Workshop on Circuits and Systems, IEICE, in 1996, respectively.

Lab Introduction

The borderless penetration of image/video transmission and archiving is a tidal tendency in modern applications. High-reality image communications are demanded by professional
experts and the general public. Some important imaging technologies have been emerged and are in progress for higher reality and deeper impression. Multi-spectral or many-primary color imaging is studied for wide-gamut color reproduction. Since the advent of super high-definition (SHD) imagery, spatial resolution and bit depth of color components are increasing; 2K/4K/8K-pixel/line in digital cinema, 40K-pixel/line for virtual slides in coming telepathology. High-dynamic range (HDR) image applications are expansive over many fields including entertainment, medicine, and archiving. High-speed CMOS image sensors allow to capture a sequence of images at a thousand frames per second or more. All of these issues increase the data rates of digital images and their quality demands innovations in image processing technology.
