Abstract For automating the harvesting of bunches tomatoes in a greenhouse, end-effector needs to reach exact cutting point and adaptively adjust pose peduncles. In this paper, method is proposed for peduncle localization estimation. Images captured real time at fixed long-distance are detected using YOLOv4-Tiny detector with precision 92.7% detection speed 0.0091 s per frame, then YOLACT + Net...

in order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at isfahan in 2012. the experimental was split plot in a randomized complete block design with three replications. in this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 n kg/ha (urea)) and barley cultivars inclu...

good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...

UNLABELLED Most commonly performed laparoscopic surgery is laparoscopic cholecystectomy. Although cholecystectomy through three port is not commonly preferred, researches have shown that it is a safe and feasible way of surgery. Material and Methods. We evaluate 100 patient that have undergone elective laparoscopic cholecystectomy through three port (group one). These patients were compared wit...

Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Developme...

An experiment was carried out using 20 native Dendrobium orchids in Completely Randomized Design (CRD) with three replications at the Orchidarium of Landscape, Ornamental and Floriculture Division, HRC, BARI, Gazipur during the period January 2007 to June 2007 to estimate genetic variability, genetic parameters and correlation coefficient among different flower components. Highly significant va...

The maize (Zea mays) spikelet consists of two florets, each of which contains three developmentally synchronized anthers. Morphologically, the anthers in the upper and lower florets proceed through apparently similar developmental programs. To test for global differences in gene expression and to identify genes that are coordinately regulated during maize anther development, RNA samples isolate...

Robotic harvesting of crops has the potential to disrupt current agricultural practices. A key element to enabling robotic harvesting is to safely remove the crop from the plant which often involves locating and cutting the peduncle, the part of the crop that attaches it to the main stem of the plant. In this paper we present a comparative study of two methods for performing peduncle detection....
