Abstract: It is the purpose of the development of ferrography to analysis of ferrography images using the computer image dispose technology.The segmentation method of ferrographic debris image is the important tache，and its segmentation effect affects recognizing precision directly.The original region growing algorithm needs the supply of the initial point selection and the growing threshold.Different supply of these data will influence the segmentation effect seriously.A new region growing algorithm is presented.It can get the initial point selection and growing threshold automatically with the help of the FCM algorithm and the fuzzy mutual information.It implements the automatic segmentation of the wear deris image.Experimental results show that the algorithm is more feasible.
