[Outline of current research] 

“A study on structure of multi-dimensional image information and communication systems of distributed shared image environment with real-time quality control”

My interests are researches and developments of visual communication systems with real-time quality control based on the cooperation of image processing and sensors, cameras and embedded distributed OS. Recently, integration of free viewpoint images and differently focused images in the frequency domain with multi-dimensional signal processing and a novel OS structure for distributed shared image environment are studied.
