image classification is an issue which utilizes image processing, pattern recognition and classification methods. automatic medical image classification is a progressive area in image classification and it expected to be more developed in the future. due to this fact that automatic diagnosis which use intelligent methods such as medical image classification can assist pathologists by providing ...

sialography is the retrograde injection of an iodinated contrast agent into the ductal system of salivary glands and this technique is the only method capable of adequately demonstrating the status of the ductal system. one of the indications of sialography is classification of the salivary ductal system fistulae. this classification has important prognostic and therapeutic values. in the prese...

in recent years, the needs of the internet are felt in lives of all people.  accordingly, many studies have been done on security in virtual environment. old technics such as firewalls, authentication and encryption could not provide internet security completely; so, intrusion detection system is created as a new solution and a defense wall in cyber environment. many studies were performed on d...

introduction: cardiovascular diseases are important factors at human death and factor destroys human resources. health intervention is a service for developing of health and diagnoses or modifies of process diseases. it is necessary that every country regarding to its goals, laws national, interests and standards, considers establishing such a system. a comparison of cardiovascular disease clas...

Fuzzy segmentation is an effective way of segmenting out objects in images containing both random noise and varying illumination. In this paper, a modified method based on the Comprehensive Learning Particle Swarm Optimization (CLPSO) is proposed for pixel classification in HSI color space by selecting a fuzzy classification system with minimum number of fuzzy rules and minimum number of incorr...

land cover is one of basic data layers in geographic information system for physical planning and environmentalmonitoring. digital image classification is generally performed to produce land cover maps from remote sensing data,particularly for large areas. in the present study the multispectral image from irs liss-iii image along with ancillary datasuch as vegetation indices, principal componen...

predicting different behaviors in computer networks is the subject of many data mining researches. providing a balanced intrusion detection system (ids) that directly addresses the trade-off between the ability to detect new attack types and providing low false detection rate is a fundamental challenge. many of the proposed methods perform well in one of the two aspects, and concentrate on a su...

the diagnosis and classification of periodontal diseases has remained a dilemma since long. two distinct concepts have been used to define diseases: essentialism and nominalism. essentialistic concept implies the real existence of disease whereas; nominalistic concept states that the names of diseases are the convenient way of stating concisely the endpoint of a diagnostic process. it generally...
