  1. Fuzzy sets and Fuzzy techniquesProjectFuzzy 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 • Cost for a given path • Minimum cost • Optimum path A fuzzy Colour Image Segmentation Applied to Robot Vision – J. Chamorro-Martinez, D. Sánchez and B. Prados-Suárez

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

  5. Results • Test image Original in RGB Membership (Object) Membership (Background) Grayscale image

  6. Results • Cell nuclei Original in RGB Membership (Object) Membership (Background) Grayscale image Membership (Object) HSI Membership (Background) HSI

  7. Results • Test image Original in RGB Membership (Nuclei) Membership (Red signal) Membership (Green signal) Membership (Background)
