A color compensation vision system for color-blind people

In this paper, we propose a color compensation vision system for color-blind people. About 8% of males and less than 1% of females have faulty color perception from birth. The degree to which a person may possess abnormal color vision ranges from slight difficulty in recognizing shades of color to total loss of color vision. Most types of defective color blindness can be classified into two categories: green color defective and red color defective. The population with the blue color defective type is less than 1%. Thus we mainly focus on a color vision compensation system that enables color-blind people to see the colors of green and red. In order to compensate image color for color-blind people, the image in RGB color space is converted to HLS color space which enables the defective color range to be easily avoided. The validity of the proposed method is confirmed by the developed camera and display color compensation system.

Development of unmanned ground vehicle for IGVC JAUS challenge

Research and development of an unmanned system for various uses is underway around the world. However, in spite of the rapidly growing market for unmanned systems, there is not yet a standard control interface for such systems. One potential standard control interface for unmanned systems is the joint architecture for unmanned systems (JAUS) originally proposed by the United States Department of Defense to develop an open architecture for unmanned systems. It is a component-based, message-passing architecture that defines a data format and methods of communication between subsystem computing nodes. This paper describes the development of a JAUS module for the IGVC JAUS challenge. Based on JAUS documents available on the Internet, we implement an actual unmanned ground system and demonstrate the validity of JAUS-compliant unmanned systems.
