Abstract Some of the changes in physiological indicators during growth and development litchi fruit grown Vietnam were studied. The length diameter fruits reached their maximum value at 10 weeks after anthesis. content chlorophyll peel its highest 6 decreased rapidly. carotenoids was low formation then increased rapidly until ripening. vitamin C reducing sugar continuously a slightly. starch li...

It is necessary to develop automatic picking technology improve the efficiency of litchi picking, and accurate segmentation branches key that allows robots complete task. To solve problem inaccurate under natural conditions, this paper proposes a method for based on improved DeepLabv3+, which replaced backbone network DeepLabv3+ used Dilated Residual Networks as enhance model’s feature extracti...
