A method based on computer vision for detection and localisation of crop rows, especially of small-grain crops, is described. The method is intended for use in a system for automatic guidance of agricultural implements in selective treatment of rows and/or inter-row spaces, e.g. with an inter-row cultivator. The computer vision system consists of a colour video camera and a computer. The camera...

A system to estimate the weed density between two rows of soybeans was developed. An environmentally adaptive segmentation algorithm (EASA) was used to segment the plants from the background of the image. The effect of two image data transformations on the segmentation performance of the EASA was investigated, and the RGB-IV1V2 transformation resulted in significantly higher quality segmentatio...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

Weed control is one of the most important technological operations to ensure crop yield and quality in ecological sugar beet production. However, conventional mechanical weed labor- time-intensive has adverse effects on soil environment. The aim this study was experimentally investigate influence robotic systems properties assess effectiveness these different methods This examines two systems: ...

The seed potato cost is very important component in total production and account for 30 to 70% which varies depending on the country or region. Tuber size an factor decide requirement per unit area. Seed affects yield, graded marketable tuber yields. Standard of 25–125 g weight (30–55 mm) known as tubers India. Obtaining achieving higher potential cultivars. profile can be reduced expanded by a...

Abstiact-This paper analyzes difficulties arising in the use of documents produced by Reverse Engineering tools. With reference to inter-modular data Row analysis for Pascal software systems, an interactive and evolutionary tool is proposed. The tool is based on: i) the production of inter-modular data Row information by static analysis of code; ii) its representation in a Prolog program dictio...

Ambient air quality datasets include missing data, values below method detection limits and outliers, and the precision and accuracy of the measurements themselves are often unknown. At the same time, many analyses require continuous data sequences and assume that measurements are error-free. While a variety of data imputation and cleaning techniques are available, the evaluation of such techni...
