Fast Approach of Color Image Segmentation

In this paper,a fast approach named as CISHF is presented to segment color image.Color image was transformed from RGB space to HSI space firstly.Then rough segmentation was done by threshold value of saturation and intensity to eliminate the noise.Finally hue data was clustered by fuzzy c-means.The formula was revised to calculate the distance from sample data to the cluster center according to characteristics of hue data.The weight of effective hue value was calculated to speed up the cluster process.Experiments show that the performance of the presented algorithm is higher than standard FCM method and better segmentation effect can be obtained.
