Image segmentation using fuzzy Lomax-Gumbel Distribution

Dillip Ranjan Nayak, Dr.Basanta Kumar Swain

Abstract: Images contain lots of uncertainties due to randomness. The contrast between the objects and the background can also be viewed as fuzzy in nature. Fuzzy approach is chosen to minimize ambiguity inherent in the images. So, different fuzzy thresholding techniques have been developed to remove the grayness ambiguity/vagueness using threshold selection. In this paper, a new fuzzy thresholding technique is introduced which processes Lomax-Gumbel probability distribution as the membership function. To show the effectiveness of the proposed method, the results are compared with fuzzy divergence method using gamma membership function. Experiments on several images show that the proposed segmentation method performs better than the existing method. Keywords: Lomax- Gumbel distribution; Fuzzy Divergence; Membership function; Thresholding; Signal to noise ratio.
