Fuzzy based Roughness Feature for Image Classification and Segmentation
Texture analysis is an emerging area in image processing. Visual texture features aim to produce visual impression by representing distinctive image details. In this paper, we propose a fuzzy based approach to extract roughness visual feature for image characterization. This proposed approach extracts significant edge details of an image and computes the roughness value by considering the intensity variation in all directions. The roughness value is then converted into fuzzy roughness value. This feature extraction method is tested for Brodatz database images. The results reveal that Fuzzy based approach leads to consistent improvement comparing with other approaches. The advantage of fuzzy based feature extraction approach has been validated by classification and segmentation using nearest neighbor algorithm.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
