The paper describes very efficient method for processing lungs images for detection of abnormality in images. The result of image shows the portion containing abnormality. The process combines various methods for image enhancement including histogram equalization, gabor and fast fourier transform for improving quality of image to optimize the result of segmentation to best configuration. The process further combines morphological functions including tophat, bottomhat and watershed segmentation to effectively separate the region of interest to detect abnormality in image. Finally the portion marked by segmentation is extracted using masking and binary thresholding to obtain the abnormal features from images.

The process combines various methods for image enhancement including histogram equalization, gabor and fast fourier transform for improving quality of image to optimize the result of segmentation to best configuration. The process further combines morphological functions including tophat, bottomhat and watershed segmentation to effectively separate the region of interest to detect abnormality in image. Finally the portion marked by segmentation is extracted using masking and binary thresholding to obtain the abnormal features from images.
