Inquisition on lesion identification based on clustering in periapical dental radiographs

In recent year's classification and/or clustering of dental radiograph for lesion detection is an active area of research. Dental radiographs imaging offers the possibility of segmentation and classification on the basis of various techniques. As dental radiograph differs from person to person the challenge is for automatic or semiautomatic computer aided analysis. Imaging is an indispensable process in the visualization of human tissues. Also, Segmenting of dental image results in caries/lesion detection in the crown, gum or pupil area. This paper present a background survey and suggesting further flow for lesion identification based on clustering in periapical dental radiographs.
