Weld Defect Detection From Imbalanced Radiographic Images Based on Contrast Enhancement Conditional Generative Adversarial Network and Transfer Learning

IEEE Sensors Journal, 2021
When a sensor data-based detection method is used to detect the potential defects of industrial products, the data are normally imbalanced. This problem affects improvement of the robustness and accuracy of the defect detection system.

Enhancement for computed radiographic images

Proceedings Eighth IEEE Symposium on Computer-Based Medical Systems, 2002
Proposes an image enhancement algorithm that converts raw data from a storage phosphor scanner into a diagnostically optimized image. The spatial segmentation algorithm is applied to extract the body part of a clinical image, and histogram analysis is then used to develop the tone-scale for the region of interest.

Enhancing Dental Radiographic Images in Spline-Type Spaces

2014 16th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2014
The aim of this paper is to propose a method to enhance the acquisition resolution of dental radiographic images to facilitate the clinical examination and interpretation. The algorithm is based on the approximation properties of spline-type spaces with multiple generators. These spaces are obtained by applying a discrete group of translation operators

A morphological image processing method to improve the visibility of pulmonary nodules on chest radiographic images

Biomedical Signal Processing and Control, 2020
A pulmonary nodular shadow on a chest radiographic image is characteristic of lung cancer. However, nodular shadows often appear with very weak contrast.

Linear Spatial Frequency Filtering for Enhancement of Radiographic Images

Radiology, 1972
Abstract One-dimensional mathematical models were used to investigate the ability of a Wiener filter, a modified Wiener filter, a simple matched filter, and an optimal matched filter to improve radiographic detection. Selective enhancement was not possible.

Influence of phosphor plate-based radiographic image specifications on fractal analysis of alveolar bone.

Oral surgery, oral medicine, oral pathology and oral radiology, 2019
OBJECTIVE The aim of this study was to evaluate the influence of spatial resolution, bit depth, and enhancement filters on the fractal dimension (FD) of photostimulable phosphor (PSP) plate-based intraoral radiographic images of alveolar bone.

Decreasing Radiation Emission in Minimally Invasive Spine Surgery Using Ultra-Low-Radiation Imaging with Image Enhancement: A Prospective Cohort Study.

World Neurosurgery, 2019
BACKGROUND Visualization of the anatomy in minimally invasive surgery (MIS) of the spine is limited and dependent on radiographic imaging, leading to increased radiation exposure to patients and surgical staff.

Refraction Effects of Diffraction-Enhanced Radiographic Imaging

Journal of the American Podiatric Medical Association, 2004
The objective of this study was to demonstrate the ability of a novel radiographic technology—diffraction-enhanced imaging—to detect contrast in bone tissue through absorption, refraction, and scatter rejection. Diffraction-enhanced imaging uses a synchrotron x-ray beam to produce images of high contrast by measuring the object’s refraction and ultra ...
