Enhancement of radiographic images in patients with lung nodules [PDF]

Thoracic Cancer, 2011
AbstractDetection of lung nodules in a chest Radiograph is very difficult due to sensitivity to noise, lighting, and similar disturbances of the blood vessels and trachea. Therefore, such images need to be carefully examined to identify and characterize lung lesions.

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
