with the growth of technology, supervising systems are increasingly replacing humans in military, transportation, medical, spatial, and other industries. among these systems are machine vision systems which are based on image processing and analysis. one of the important tasks of image processing is classification of images into desirable categories for the identification of objects or their sp...

Image segmentation is a fundamental approach in the field of image processing and based on user’s application .This paper propose an original and simple segmentation strategy based on the EM approach that resolves many informatics problems about hyperspectral images which are observed by airborne sensors. In a first step, to simplify the input color textured image into a color image without tex...

one of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. several edge detectors have been developed in the past decades, although no single edge detector...

the studies in aerial vehicles modeling and control have been increased rapidly recently. in this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (uav) and unmanned ground vehicle (ugv) is considered. in this paper the uav plays the role of a virtual leader for the ugvs. the system consists of a vision- based target detection algorithm that uses the ...

introduction: the image quality as well as film speed is influenced by the film processing conditions. different combinations of films and processing methods affect the diagnostic accu-racy. temperature and developer exhaustion result in different image quality. the purpose of this study was to evaluate the influence of film type and processing conditions on caries detec-tion.  material and met...

physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...
