Abstract

In this paper, a new active learning method is proposed, which distinguishes between crop and weed based on their different spectral reflectances. A method comprising novel detection and incremental class augmentation was implemented. Novel detection was based on one class classifiers. Under field conditions, crop and weed species can be recognised successfully. Best results for the active learning were obtained for the one-class Mixture of Gaussians (MOG) and Self Organising Map (SOM) classifiers. The MOG and SOM performance in crop recognition was 100% and 96% respectively while the recognition for different weed species ranged from 31-98% (MOG) and 43-94% (SOM).
