1. Fuzzy sets and Fuzzy techniques Project Fuzzy color image segmentation Amin Allalou Amalka Pinidiyaarachchi

2. Method A region growing processing to segment color images A region – Fuzzy subset of connected pixels –Constructed using color information To guide the region growing process –Distance defined in color space is used The color distance is used both –To select the pixels which will be linked in each step –To calculate membership degree at each point to each region

3. Distance between pixels A fuzzy Colour Image Segmentation Applied to Robot Vision – J. Chamorro-Martinez, D. Sánchez and B. Prados-Suárez Cost for a given path Minimum cost Optimum path

4. Membership function for fuzzy regions Membership degree of a pixel to a fuzzy region
