Performance of Compound Enhancement

Algorithms on Dental Radiograph Images

Abstract—The purpose of this research is to compare the original

intra-oral digital dental radiograph images with images that are

enhanced using a combination of image processing algorithms. Intraoral

digital dental radiograph images are often noisy, blur edges and

low in contrast. A combination of sharpening and enhancement

method are used to overcome these problems. Three types of

proposed compound algorithms used are Sharp Adaptive Histogram

Equalization (SAHE), Sharp Median Adaptive Histogram

Equalization (SMAHE) and Sharp Contrast adaptive histogram
