Threshold Based Lung Image Segmentation with Robust Artificial Bee Colony Algorithm Optimization Technique

Abstract: Image segmentation is a complex task which helps us to extract information for analysis a digital image. Millions of methods are available for image segmentation. Out of that image thresholding is a simple, efficient and frequently adopted method for image segmentation. Thresholding basically divide a digital image into two regions; foreground and background based on the intensity value of the pixels. The key point in image thresholding is on the optimum value of threshold of the digital image. It is an important and crucial task to select the optimum threshold. A false choice of threshold will lead to poor results in image segmentation. Generally optimization algorithms are used to select the optimum threshold value. Artificial Bee Colony (ABC) algorithm is one of the optimization algorithms which are the replica of natural behaviour of honey bees to find abundant nectar amount. This study describes an approach to segment an 8 bit human lung image using artificial bee colony algorithm based thresholding method. The proposed method proves that the uniformity factor in the image segmentation is good relative to other conventional methods.
