Existing image manipulation techniques such as cropping works well for images(More)
There are many image retrieval systems today. These systems, however, are difficult to use in outdoors. In this paper, we propose an image retrieval system of flowers that can be used for mobile computing environment.

Web handling is an important issue in printing machine for improving the performance of printing products. In the multi-colors printing machine which is consist of multi-printing units, the dynamics of each unit are coupled and the signal propagation is always with delay. This paper presents a delay-dependent nonlinear control approach for a three colors(More)
A picture is one of important research subjects in order to make our life spiritually rich. Most studies on pictures, however, only propose some substitute functions of actual drawing or painting materials. There is no system that evaluates pictures drawn by users and gives advice about them. We propose a learning support system for basic techniques in(More)
