Abstract
Segmentation is a efficient technique of dividing the image into different regions or segments. Most of the researchers took clustering as the best method of segmenting an image. In clustering we try to increase the similarity within a same class and decrease the similarity between the classes. Many clustering algorithms were developed like FCM, FLICM and FELICM which are considered as the best algorithms to cluster the data. In our paper, we combine FELICM (Fuzzy Edge and Local Information C-Mean) with the negative selection algorithm. Negative selection algorithm is an evolutionary method which is based on artificial immune systems. The proposed method result shows us high accuracy results and even solves the problem of over segmentation.
1. Introduction
Image Segmentation is a critical methodology of image transforming and comprehension in digital image processing. This technique is basically used for separating the image into different parts of homogeneity. The motive of image division is to enhance the representation of a picture into something that is more important. The basic use of it is to find the location of objects, boundaries, lines etc. in the digital images. Clustering is a way in which a data set or say pixels are interchanged by groups, pixels may place together because of the same color, composition etc.
5. Conclusion
The previous clustering method gives the isolated samples of pixels so mostly it results in isolated regions. Traditional clustering methods are unable to remove isolated regions. FLICM produces boundary zones. FELICM somehow eliminates these problems, but the proposed method gives very efficient result as compared to previous clustering methods. Moreover, it also eliminates the over segmentation which can be clearly seen in the Matlab inbuilt images result. In our proposed methodology when FELICM is integrated with the negative selection algorithm, the three of the parameters i.e. PSNR value, accuracy and entropy are showing the improved and better results when it is compared with the existing FELICM.
