    In order to design industrial products fitting well to the human body, it is necessary to make full use of information of human anatomical landmarks. However, the surface data, measured by 3D scanner, is not set the coordinate system. So, the specialists pasted the scannable markers to the parts of the body beforehand so as to set the coordinate system. Here, pasting the markers had the problems such as time consuming for the specialists and psychological load to the customers. We propose an automatic detection method of the basic landmarks used for defining the coordinate system, MT(metatarsale tibiale) and MF(metatarsale fiburale), from the point cloud of a human foot using regression analysis. Then the coordinate system of the foot model is defined by using these obtained MT and MF. Then, we attempt to improve the accuracy by the Free Form Deformation method.

    This paper proposes a new real-time video editing system that can enhance the emotion. This system can be applied as a communication tool like a video chat. First, this system recognizes the facial expressions by using two CCD cameras. Then, user′s emotion is enhanced by controlling the facial-color according to the recognized facial expression. In this system, a real-time skin pigment control method with Graphics Processing Unit(GPU) is used for controlling the high-realistic facial-color. In the facial emotion recognition, face tracking and recognition are performed only using the color information to achieve the real-time processing. Finally, we evaluate the effectiveness of the developed system, then high effectiveness for the emotion enhancement is obtained.

    In this paper, the authors discuss how to involve the heat sensation in image creation by using thermal vision. The past work of the authors presents a novel input system which can detect temperature change on a sensing surface when objects hotter or colder than the surface touch it. This can be a promising user interface platform involving the heat sensation interaction in image creation. Applications of image modification and 3D shape model deformation are implemented on the platform. The image modification application aims to achieve an intuitive user interface for color saturation and hue modifications which are strongly related to heat sensations. Using the analogy of thermal plasticity, the authors propose an intuitive manipulation method of deforming 3D shape models as making glassworks in the 3D shape model deformation application.

    An autumn coloring is essential natural phenomena for Computer Graphics (CG) to express seasonal impressions. Since natural autumn colorings possess both temporal and spatial complexity, few works study autumn coloring related to this complexity. We study a method preserves both temporal and spatial autumn coloring complexity using Fractal Top Function that maps the complex geometrical space of both trees and leaves to a code space. We propose the algorithm that progress autumn colorings including both the tree-level and leaf-level of autumn colorings using an RIFS (Recurrent Iterated Function System).

    Recently, due to the widespread use of computers, text-based communication methods, such as e-mail, blog, and chat, have attracted a great deal of attention. Moreover, various communication media, such as picture and movie, are used for expressing own emotion. If pianists can apply their musical expressions to the text input, they can input texts with their own emotion richly. Therefore, the goal of our study is to construct TEMPEST (TExt input and Musical PErforming SysTem) that is a text input system to input texts with various musical expressions by using a MIDI keyboard. Since this system provides text input methods considering musical artistry, a performer can input texts like playing music. As the result of a questionnaire evaluation, it proves that proposed methods have high effectiveness for expressing emotion in inputting texts.
