Color image analysis using fuzzy set theory
Yung‐Sheng Chen, Hui-Yu Hwang, Bor-Tow Chen · Proceedings - International Conference on Image Processing · 2002
An application of fuzzy set theory to the color image analysis is presented in this paper. It is developed to inference the weather state from a color image. For a color image, its RGB components are first converted into HSI components. For each component, a 3-layer quadtree is created for image analysis. Then the histogram of each block image from the top layer to bottom layer is computed. The histogram is further converted into a membership function by using the scheme of a 6-parameter fuzzy number. The fuzzy inference for the given image is thus achieved by using the generated membership functions.
