| Abstract: | Feature extraction is an important step in image targets recognition.This paper analyses the applications of quaternion in color image processing,and thus puts forward the arithmetic of RS color image waters feature extraction based on quaternion.The result of experiment indicates that the arithmetic has obvious advantage and adaptability. |
