feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of local binary pattern features. in this paper, we investigate the use of local binary patterns for percep...

introduction: due to penetration of pathogenic bacteria into the periodontal tissues in moderate to severe periodontitis, the mechanical methods are not sufficient in these cases. therefore, administration of local/systemic antibiotic is recommended following mechanical root debridement. however, side effects of antibiotics such as microbial resistance and patient allergy led to development of ...

We present a fast, interactive local rigid registration application to localize tumour’s position for radiotherapy. The aim of the application is to automatically localize in a therapy CT dataset the target volume marked in a plan CT before applying a therapy. The algorithm is fast because it restricts the registration to a small area of the whole dataset. Once the target is found, the applicat...

Cellular manufacturing system, an application of group technology, has been considered as an effective method to obtain productivity in a factory. For design of manufacturing cells, several mathematical models and various algorithms have been proposed in literature. In the present research, we propose an improved version of discrete particle swarm optimization (PSO) to solve manufacturing cell ...

We propose a technique of local application of one-level decision and regression trees. We recognize local regions having similar characteristics and then build local expert on each of these regions describing the relationship between the data characteristics and the target value. We performed a comparison with other well known lazy methods on standard benchmark datasets and the proposed techni...

Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...
