This paper presents a novel vision based technique for navigation of agricultural mobile robots in orchards. In this technique, the captured color image is clustered by mean-shift algorithm, then a novel classification technique based on graph partitioning theory classifies clustered image into defined classes including terrain, trees and sky. Then, Hough transform is applied to extract the features...
Robotisation of forestry harvesting in New Zealand has the potential to achieve great productivity benefits and support the timber industry in the face of global market competition. Recognition and localization of tree trunks is the first critical operation for an autonomous forestry harvesting robot and is a challenging task due to variations of illumination under normal forestry harvesting conditions...
this paper reports an automated tracking and force measurement system for C. elegans in motion, based on microscopy computer vision. A polydimethylsiloxane (PDMS) device was microfabricated to allow C. elegans to move in a matrix of micropillars in a channel. An image processing algorithm has been developed to track the worm and deflecting micropillars automatically in purpose of quantifying multipoint...
