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...

In this paper, a defect grading method for digital radiographic images from CMOS x-ray linear array detector was put forward, which is based on a standard defect-grading comparison sample and a computer-aided defect interpretation method. A standard defect-grading comparison sample was designed and used to help measuring the distortion and magnification of the images, and to grade the defects i...

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 ...

BACKGROUND: Knowledge of the accuracy of chest radiograph findings in acute lower respiratory infection in children is important when making clinical decisions. METHODS: I conducted a systematic review of agreement between and within observers in the detection of radiographic features of acute lower respiratory infections in children, and described the quality of the design and reporting of stu...

Introduction rthopaedic evaluation of hip pain in the young adult population has undergone a rapid evolution over the past decade. This is in large part due to enhanced awareness of structural hip disorders, including developmental dysplasia of the hip and femoroacetabular impingement. Surgical treatment for these disorders continues to be refined, and our ability to identify patients along the...
