This work proposes the development of an embedded real-time fruit detection system for future automatic fruit harvesting. The proposed embedded system is based on an ARM Cortex-M4 (STM32F407VGT6) processor and an Omnivision OV7670 color camera. The future goal of this embedded vision system will be to control a robotized arm to automatically select and pick some fruit directly from the tree. Th...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

this study was carried out to examine the effects of kaolin spray for reducing the adverse effects of high radiation and temperature, especially on fruit sunburn in apple. treatments were four concentration of kaolin (0, 2, 4, and 6%) and two important and commercial apple cultivars in fars province; ‘golden delicious’ and ‘starking delicious’. trees physiological parameters, fruit sunburn and ...

People perceive roughly constant surface colors despite large changes in illumination. The familiarity of colors of some natural objects might help achieve this feat through direct modulation of the objects' color appearance. Research on memory colors and color appearance has yielded controversial results and due to the employed methods has often confounded perceptual with semantic effects. We ...

ABTRACT 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 an unsupervised segmentation algorithm through a multiresolution approach which uses both color and edge information. The use of a Quadtree ...

Irrigation with moderate salinity stress in a hydroponic system improves the inner and outer fruit quality of tomato (Solanum lycopersicon Mill. ‘House Momotaro’). We investigated the effects of 50 mM NaCl in a hydroponic solution on the levels of various metabolites, including soluble sugars, amino acids, and organic acids, and on the expression levels of salinity-responsive genes during fruit...

a study of two years was carried out on apples, red delicious cv. in comeh of semirom region. the objective of this research was to assess the effect of pre-harvest calcium phosphate (seniphos) spraying and summer pruning on the skin color and quality characteristics of the fruit. study was carried out using a complete randomized block design with 3 replications. trees were subjected to pre-har...

The color of tomato fruit is mainly determined by carotenoids and flavonoids. Phenotypic analysis of an introgression line (IL) population derived from a cross between Solanum lycopersicum 'Moneyberg' and the wild species Solanum chmielewskii revealed three ILs with a pink fruit color. These lines had a homozygous S. chmielewskii introgression on the short arm of chromosome 1, consistent with t...

tomato production, growing nearly 40 percent of world supply. The majority of fruit is processed into concentrated paste, but an increasing percentage is being used for products utilizing peeled fruit, either whole or diced. Important fruit quality attributes for paste production are soluble solids content (SS) and color of the blended product. Uniformity of color is more important for peeled f...

In this article we present the results of an unsupervised segmentation algorithm based on a multiresolution method. The algorithm uses color and edge information in an iterative minimization process of an energy function. The process has been applied to fruit images to distinguish the different areas of the fruit surface in fruit quality assessment applications. Due to the unsupervised nature o...
