A Research Paper on Lung Field Segmentation Techniques using Digital Image Processing

Abstract

In this review study, we investigate various strategies for lung field segmentation by utilizing digital image processing. In chest radiographs (CXRs), lung field dissection segmentation is and will continue to be a crucial phase in the process of automatically evaluating pictures of this kind. We describe a method for the segmentation of the lung field that is based on a boundary map of high quality that was detected using a structured edge detector, which is a contemporary border detector (SED). A SED has previously been trained to recognize lung limits by using manually delineated lung sections in CXRs as training data. Following this step, the masked and tagged boundary map is converted into the active contour map (ACM). In conclusion, the lung contours that are created by following filter phases that are based on Gaussian and dilate features are the contours that have the highest rate of trust in the ACM. Our method is evaluated using aberrant lung pictures obtained from chest x-rays, and it is demonstrated to be superior, in terms of the amount of processing time required, to segmentation utilizing a universal contour map.
