Research of Radiographic Image Enhancement Technology

Advanced Materials Research, 2013
mage enhancement has applied widely in biomedical, nondestructive testing, satellite remote sensing and other fields. Especially for the low contrast radiographic images, usually there are some disadvantages for a radiographic image such as the local area image does not show a striking contrast.

RADIOGRAPHIC IMAGE ENHANCEMENT USING HYBRID ALGORITHM

Jurnal Teknologi, 2016
Radiographic image quality is important in the medical field since it can increase the visibility of anatomical structures and even improve the medical diagnosis. Because the image quality depends on contrast, noise, and spatial resolution, images with low contrast, a lot of noises, or low resolution will decrease image quality, leading to an incorrect

Multi‐step radiographic image enhancement conforming to weld defect segmentation

IET Image Processing, 2015
To improve the accuracy of automatic defect segmentation in radiographic non‐destructive testing and evaluation, the authors proposed a multi‐step radiographic image enhancement algorithm (MSRE) conforming to weld defect segmentation. In this algorithm, the requirement of defect segmentation is fully considered when enhancing a radiographic testing ...

Adaptive Contrast Enhancement for Digital Radiographic Images using Image-to-Image Translation

Current Directions in Biomedical Engineering
Digital radiography in medicine is a widely used imaging method for obtaining visual information about the inside of a body. To prepare the acquired raw image for diagnostic evaluation, the contrast must be adjusted depending on the examined part of the ...

Comparison of Accuracy of Conventional Periapical Radiography and Direct Digital Subtractions Radiography with or without Image Enhancement in the Diagnosis of Density Changes

Journal of Dental Research, Dental Clinics, Dental Prospects, 2012
Background and aims. In periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. This study was aimed to compare visualization

Radiographic Image Enhancement by Wiener Decorrelation

, 1992
The primary focus of the application of image processing to radiography is the problem of segmentation. The general segmentation problem has been attacked on a broad front [1, 2], and thresholding, in particular, is a popular method [1, 3-6]. Unfortunately, geometric unsharpness destroys the crisp edges needed for unambiguous decisions, and this ...

Radiographic image enhancement. Part I: spatial domain techniques

Dentomaxillofacial Radiology, 2001
Abstract Digital image enhancement techniques provide a multitude of choices for improving the visual quality of diagnostic images. Appropriate choice of such techniques is greatly influenced by the imaging modality, task at hand and viewing conditions. This sequence of two articles will provide an overview of underlying concepts, along with algorithms
