A robust color image segmentation method based on weighting Fuzzy C-Means Clustering (RWFCM) is proposed for color image segmentation. The first component of color feature set is chosen as the one-dimensional eigenvector. In order to reduce the computational complexity, the mapping from pixel space to eigenvector space is used for modifying the object function. Feature distance which is applied to...
This study presents a laser/vision-based tracking of people in 3D space. A sensor node consisting of a two-layered laser-range scanner (LRS) and fisheye camera is placed in an environment. LRS detects the heads and knees of people, and the camera captures the color images of people detected by the LRS. From the position data of people scanned by LRS, peoples' motion in the horizontal plane is tracked,...
We propose and implement a solution for applying an infrared radiation (IR) image sensor to step-on interface (SOI). SOI is a kind of natural human-robot interface what consists of a projector and a laser range scanner (LRG) sensor. And it enables any interactive touch applications on desktop or floor. We attempt to introduce an IR image sensor such as ASUS Xtion to SOI instead of LRG sensor. In this...
“Kawaii” is a Japanese word that represents an emotional value; it has positive meanings, such as cute, lovable, and small. In the 21st century, the emotional values of industrial products become very important. However, since not many studies have focused on the kawaii attributes, we focus on a systematic analysis of kawaii products themselves, that is kawaii feelings caused by the attributes such...
