Enhancement Method of Root Canal Image in Dental Film Based on Ridgelet Transform

QIU Ju,ZHANG Zhong-bo,MA Si-liang(Institute of Mathematics,Jilin University,Changchun 130012,China)  
On the basis of the property of dental film and the characteristics of ridgelet transform maintaining linear structures this paper presents an edge detection method based on ridgelet transform.The Radon transform connects the Gaussian wavelet and ridgelet.By means of this method one can obtain the continuous edge from the root canal image accurately by comparison the gray level mean in the ridgelet domain.The experimental results show the method can denoise greatly,determine the location accurately and benefit the diagnosis and treatment.
