A Kernel-Modified SVM Based Computer-Aided Diagnosis System in Initial Caries

Clinical initial caries appear as no obvious difference to normal ones in X-ray images. Researchers attempt to set up computer-aided system to facilitate clinical initial caries diagnosis. This paper mainly made two efforts, image enhancement using watershed and modification of SVM kernel function. Experiments show that the testing accuracy of the kernel-modified SVM caries detection is improved compared to the former research, and the image enhancement helps dentists to find caries easier.
