This paper describes a method of giving impression words for images based on colors. 160 impression words are prepared, and colors which are strongly related to each of the 160 impression words are registered into the system in advance. In this system, we adopt Lab color space which is a color coordinate system and can obtain exact color difference between pixels and extract main colors of images based on the results of clustering in Lab color space. The number of main colors of an image is determined when the sum of pixels of the main colors is larger than 85% of all the pixels in the image, and the colors with the larger number of pixels are determined in ascending order. We propose a distance between the main colors and the registered colors. In this system mCn combinations of distances between m colors registered in an impression words and n main colors are obtained. Using the mCn distances, we calculate a minimum distance and an average distance every 160 impression words. By the comparison of the minimum distance and the average distance of each impression word, the system determines suitable impression words for the image. Experimental results show the proposed method to be effective.

本論文では, ファジー推論法による非線形なPID制御と線形なPID制御の, 従来法と比較してより簡便で実用的な実現法について提案を行う. ここでの提案は, 簡略化することで推論計算の高速化を図ったファジー推論法の簡略化直接法を, わずか6個の簡単な構造を有するファジー制御規則に適用することにより, PID制御器に準拠した非線形なPID制御のみならず, 線形なPTD制御をも容易に実現できるという方法である.
