To deal with the contradiction of classical pixel based on classification approaches cannot satisfy the requirements of High Resolution Image (HRI) classification.Feature Enhancement Techniques Combined with Object-Oriented Classification Approach (FETCOOCA) is provided.Considering the difference of the objects in terms of spectrum, shape, texture etc.contained in HRI, some feature enhancement techniques are carried out on the area of water body, vegetation, and constructions.To test the overall accuracy of FETCOOCA classification result image, FETCOOCA is performed using SPOT5 image, which located in Haidian District, Beijing, China.Finally, a comparison between FETCOOCA and classical pixel based classification approaches is carried out.The study proved that: for HRI classification, FETCOOCA has much better classification result than classical pixel based classification approaches.It can significantly improve the overall classification accuracy of HRI, can avoid the pepper and salt phenomena, and have rich syntax information which is easy for image interpretation.
