Title Gloss Measurement Using Psychological Visual Characteristics
Abstract With the development of technology and the expansion of productions scales, the improvement of the product quality has become a more important issue than that of the quantity. Because human senses about gloss, glare, and image-sharpness highly affect the quality of the product, equation-based definitions which integrate the physical fitness qualities of a product are commonly used to describe such indexes. Accordingly, calculation using these equations may show results which are quite different from the perception of human beings. Therefore, in this study, we propose a new gloss measurement method using visual characteristics. Simulation results show that the glossiness obtained through this new method agrees well with the psychological sense of human beings.
Three issues are stressed in this speech as follows: (1) The problem with the conventional methods — glossiness measured does not agree with humans’ psychological sense; (2) Explanation on how to quantify glossiness from the perspective of psychological sense; (3) Focus is given to a new gloss measurement method. The fitness of psychophysical glossiness is largely improved when visual characteristics are taken into account. A simplified model is also introduced to better clarify the mechanism of human beings’ gloss perception.

Title The Levitation Mass Method – A precision force measurement method using an optical interferometer and a levitated mass
Abstract A method for precision force measurement, i.e. the levitation mass method (LMM), which has been proposed and improved by authors, are reviewed. An rigid object is levitated with a small friction using an aero-static linear bearing. The total force acting on the object (the moving part of the bearing) is measured as the product of mass and acceleration of the object, i.e. F=Ma. In the method, only the Doppler shift frequency of the laser beam reflected by the object is accurately measured using an optical interferometer. Subsequently, the velocity, position, acceleration, and inertial force of the object are calculated from this frequency.

Title Challenges of Activity & Behavior Analysis
Abstract Action/activity and behavior analysis are very important research areas in computer vision and man-machine interaction. Over a decade, a great number of methodologies have been proposed to solve different problems regarding these topics. However, due to various complex issues, a number of key challenges still remain unexplored. Therefore, various aspects of human activity and behavior analysis will be covered in this keynote speech. The talk will also cover challenging research aspects to explore in future.
