Objectives: In restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. The present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (PSPs). Methods: a whole numb...

It is necessary to detect suspected defect regions in the radiographic weld images to find the flaw and its causative factors. This requires processing of radiographic images by a suitable approach This paper presents an image processing approach to process incomplete penetration type flaws in radiographic images of the weld specimens considering morphological aspects of the image. In the prese...

Image processing and image analysis are the main aspects for obtaining information from digital image owing to the fact that this techniques give the desired details in most of the applications generally and Non-Destructive testing specifically. This paper presents a proposed method for the automatic detection of weld defects in radiographic images. Firstly, the radiographic images were enhance...

Digital Image enhancement provides a multitude of choices for improving the visual quality of radiographic images. When the details of radiographic image are lost due to various reasons, image enhancement has been applied. Many algorithms have been proposed for image enhancement in the past decade. Contrast improvement algorithms are used to enhance image contrast and some algorithms come with ...

Radiographic inspection is a reliable non-destructive test, widely used for integrity evaluation of structures and equipments. Nowadays, high quality images with very accurate resolutions have been supported by modern digital radiographic systems. However, the image analysis for internal defect detection and geometric characterization is still a not totally automated task. The main reason is th...

PURPOSE The aim of this study was to evaluate the feasibility of applying the high dynamic range (HDR) technique to radiographic imaging to expand the dynamic range of conventional radiographic images using a colored multiexposure approach. MATERIAL AND METHODS An appropriate study object was repeatedly imaged using a range of different imaging parameters using a standard clinical x-ray unit....
