potato image segmentation is an important part of image-based potato defect detection. this paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on genetic algorithm (ga) optimization and morphological operators. the proposed potato color image segmentation is robust against variation of background, distance and ...

The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...

abstract cognizing environment in human vision-system is complex process. part of this process is perceiving image elements and attention signals in general. in the other hand, extracting special description from image elements. it is assumed that the environment scene is a kind of image. according to this description, it is justifiable to interpret image according to the gestalt theory princip...

abstract—digital foot scanners have been developed in recent years to yield anthropometrists digital image of insole with pressure distribution and anthropometric information. in this paper a hybrid algorithm containing gray level spatial correlation histogram and shanbag entropy is presented for analysis of scanned foot images. an evolutionary algorithm is also employed to find the optimum par...

Many advances in dermatology have been made in recent years. In the present review article, newly described disorders from the last six years are presented in detail. We divided these reports into different sections, including syndromes, autoinflammatory diseases, tumors, and unclassified disease. Syndromes included are "circumferential skin creases Kunze type" and "unusual type of pachyonychia...

volume estimation of most agricultural products using mathematical methods is not accurate because of their irregular shape. an alternative method is image processing, which can be used in continuous sorting machines. the objective of this study is to find a practical method for volume estimation of potatoes using image processing. fifty potatoes (marfona variety) were selected as experimental ...

Function-described graphs (FDGs) have been introduced very recently as a representation of an ensemble of attributed relational graphs (ARGs) for structural pattern recognition 1, 2]. In this paper, the relationship between FDGs and Random Graphs 3] is analysed and the synthesis process of FDGs is studied, whereas the matching process between FDGs and ARGs is discussed elsewhere 4]. Two procedu...
