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

• Cost for a given path
• Minimum cost
• Optimum path
