variations in lighting are a problem for visual systems. in the current research, a new thresholding method using a 3d euclidian elliptical surface was defined and applied for plant detection purposes. the results showed that this method had lower type i error, type ii error, total error and mean square error compared with those of conventional segmentation methods. the method was evaluated for...

Fernández-León M.A., Lozano M., González D., Ayuso M.C., Fernández-León M.F. (2014): Bioactive compounds content and total antioxidant activity of two savoy cabbages. Czech J. Food Sci., 32: 549–554. The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified a...

The discrete element parameters of cabbages (Brassica oleracea L.) were calibrated for the design and parameter optimization a cabbage harvester. model was created based on study material characteristics simulation calibrated. intrinsic partial contact obtained by direct measurement. accumulation angle determined plate drawing test. Through steepest ascent test orthogonal rotation combination t...

The effects of commercial vermicomposts, produced from food waste, on infestations and damage by aphids, mealy bugs and cabbage white caterpillars were studied in the greenhouse. Vermicomposts were used at substitution rates into a soil-less plant growth medium, MetroMix 360 (MM360), at rates of 100% MM360 and 0% vermicompost, 80% MM360 and 20% vermicompost, and 60% MM360 and 40% vermicompost t...

In Japanese agriculture, labor shortages are becoming increasingly severe due to the lack of farmers and aging. Therefore, extensive research has been conducted on automation cabbage harvesting. automatic harvesting, detection is performed using deep learning. evening hours, if backlight enters camera, not possible. Moreover, cabbages in back row that be harvested detected targeted for harvest....

One noticeable feature that is shared by cabbages, leeks, garlic and onions, amongst others, is their strikingly pungent aroma and distinctive taste, mostly attributable to sulphur-containing chemicals. Indeed, it has been appreciated for many years that these vegetables contain large amounts of sulphurous materials that release volatile compounds, especially during the processes involved in fo...

By the principle of possibilities, we understand what an entity is with reference to what it could have been. The word red, for example, belongs to both a domain of lexical possibilities (all English words) and a domain of conceptual possibilities (all conceivable denotations). But on any occasion, the word is intended to be understood against much narrower domains. Speakers and addressees rest...
