Abstract
So far, the observations of lungs from the X-ray image of the thorax have been done manually by a physician or radiologist, the results obtained are generally subjective. Therefore, it is needed to have medical aids that can provide an objectively better analysis and can be used in various areas, such as lungs mass screening (thorax). In this research, an application for segmenting lungs from the thorax x-ray image is developed using geometric active contour and analysis of histogram equalization filtering.
This study used 20 X-ray images of the chest cavity (thorax). Performance results of the test in the geometric active contour segmentation showed the sensitivity of 77.12%, accuracy of 95.88% and specificity of 98.85% for the right lung and the sensitivity of 81.09%, accuracy of 96.28% and specificity of 99.33% for the left lung.
