DIGITAL RADIOGRAPHIC IMAGE ENHANCEMENT FOR IMPROVED VISUALIZATION
Nisar Ahmed, Waqas Ahmed, Sheikh M. Arshad · 2011
Digital radiographic image enhancement techniques are used to accentuate and sharpen image features for enhanced visualization and better quality images. Image enhancement does not try to quash the artifacts it just makes it easier to interpret by improving visualization. Different techniques are available to reduce visual noise, enhance edges and display improved contrast images. Digital radiographic images with low contrast, visual noise due to electrical noise or X-ray scattering and blurring caused by complexity of body tissues, can worsen the result of diagnostic. So it is necessary to enhance radiographic images to improve their visual quality, including contrast enhancement and feature enhancement. Different techniques to enhance digital radiographic images have been presented in this paper. Furthermore a graphical user interface has been made in MATLAB to show the results of digital radiographic image enhancement techniques. The objective is to incorporate radiologists to optimize the diagnostic quality of radiographic images.
