  2. 1. Vision Based Perception for Mechatronic Weed Control

    Author : Björn Åstrand; David Slaughter; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots;

    Abstract : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. READ MORE

  4. 2. Crop and weed discrimination using computer vision

    Author : Maria Persson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Crops; Weeds; Other information technology; Övrig informationsteknik;

    Abstract : The thesis is concerned with computer vision in ecological and precision agriculture aiming to identify crops and weeds in images of crop rows. The identification of plants can be done by extracting the plants in the image and classifying them as a crop or weed depending on the shape and color. READ MORE

  6. 4. Weed seed predation : a promising ecosystem service in agriculture

    Author : Eirini Lamprini Daouti; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Enhancing biodiversity and promoting vital ecosystem services can reduce the global dependence on anthropogenic inputs in agriculture while securing crop yield. Weed infestation can severely reduce crop yield but the dominance of herbicides for weed control can impair human health, beneficial organisms and ecosystem service delivery. READ MORE

  7. 5. Population dynamics of the perennial weed species Sonchus arvensis L

    Author : Saghi Anbari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Sonchus arvensis L. is a perennial weed that is widely prevalent in annual crops in northern Europe and can cause substantial yield losses. The abundance of S. arvensis has increased recently, primarily due to expansion of organic farming and increased use of reduced tillage. READ MORE
