In this paper, LBP and its variant were tested on Family Face Database which was constructed in the earlier work by the author [1] in the framework of personal image management system. The combination of LBP and other features were also tested for comparison. In addition, several illumination normalizing methods, dissimilarity measures and sub-block divisions were also tested in our framework.
Recently, several robotic/intelligent wheelchairs that have autonomous functions to get to some goals or user-friendly interfaces, have been proposed. Although it is desirable for wheelchair users to go out alone, caregivers often accompany them. Therefore it is important to consider reducing caregivers' load and support their activities. Hence, we have proposed a robotic wheelchair that can move...
This paper proposes an interactive texture design method to obtain adequate texture patterns for 3D computer graphics shapes. Texture mapping is widely used to improve the visual richness of surface appearances. Designing texture patterns can be a problem to search an adequate pattern for the 3D shapes in the scene physically and psychologically. So it is required to supply intuitive and simple method...
Recently, our society is rapidly aging, and it's getting more important to evaluate swallowing function for preventing accidents and illness such as aspiration pneumonia. So we developed a new evaluation system for swallowing function. This system can evaluate swallowing function safely and quantitatively without touching by a Fiber grating vision sensor which is a kind of 3D scanning sensor using...
A novel scheme for construction and representation of a single compound cable is presented. The complicated geometry of those objects put on natural posture is analysed and represented based on a modified clustering method: Outer Edge FCM. In the modification, the membership functions can be extended by introducing three evaluation functions for distance, angle, and reach, respectively. We introduce...
This paper discusses a 3D shape measurement device based on an image scanner. Our shape reconstruction method using the image scanner is one of the photometric stereo method applied to multiple linear light sources. This method is constructed by several processes. First, we estimate the heights of object from the scanning plane to object's surface using four images taken by two pairs of two linear...
