Many segmentation techniques are available in the literature and some of them have been widely used in different application problems. Most of these segmentation techniques were motivated by specific application purposes. In this article we present the preliminary results of an unsupervised segmentation algorithm through a multiresolution method using color information for fruit inspection task...

One of the important quality features of fruits is its appearance. Appearance not only influences their market value, the preferences and the choice of the consumer, but also their internal quality to a certain extent. Color, texture, size, shape, as well the visual flaws are generally examined to assess the outside quality of food. Manually controlling external quality control of fruit is time...

During its evolution and domestication Solanum lycopersicum has undergone various genetic 'bottlenecks' and extreme inbreeding of limited genotypes. In Europe the tomato found a secondary centre for diversification, which resulted in a wide array of fruit shape variation given rise to a range of landraces that have been cultivated for centuries. Landraces represent a reservoir of genetic divers...

In the framework of collection and identification of fungi of Zagros mountains (W and SW Iran), specimens of agaric fungi with subterraneandevelopment were collected from oak forests in Chaharmahal-va-Bakhtiari province. Native people of Dopolan and Rahimabad used hypogeous fruit-bodies of fungus as edible fungi. Excavation was done and fungal samples were found at 15–30 cm soil depth, near Oak...

The functional or structural linkage among traits [phenotypic integration (PI)] within complex structures can constrain the evolutionary response of individual traits. To analyse whether frugivores with distinct sensory ecology have shaped the patterns of fruit diversification differently, we compared PI values of fleshy fruits that are consumed by birds and mammals. We used phylogenetic compar...

Tomato (Solanum lycopersicum Mill.) represents a model species for all fleshy fruits due to its biological cycle and the availability of numerous genetic and molecular resources. Its importance in human nutrition has made it one of the most valuable worldwide commodities. Tomato fruit size results from the combination of cell number and cell size, which are determined by both cell division and ...

pears (pyrus spp.) belongs to the rosaceae family, which have been cultivated formore than 3000 years. pears are among the most important fruits in all the temperateregions in about 50 countries of the world. the objectives of this study were to classifypear genotypes based on qualitative and quantitative characteristic and determination oftheir genetic distance. evaluation of genetic diversity...

In seed-dispersal mutualisms, the number of fruit a plant displays is a key trait, as it acts as a signal for seed dispersers that entails fruit removal and exportation of reproductive units (fruit crop size hypothesis). Although this hypothesis has gained general acceptance, forces driving the shape and strength of natural selection exerted by birds on fruit crop size remains an unresolved mat...

A total of 117 pomegranate genotypes collected from different areas of Yazd province of Iran were studied for genetic variation by evaluating 23 morphological traits according to the international descriptor. Similar diversity pattern of the measured characteristics was observed in three types of sweet, sweet-sour and sour varieties. The traits shape of fruit base, suckering tendency, vigor of ...
