On-line measurement of selected soil properties towards the refinement of Nitrogen fertilisation management in vegetable crops [PDF]

open access: yes, 2015
Fertiliser applications in vegetable crops are one of the main input costs of production. Thematic soil maps have been widely used for decades to characterise soil nutrients and, therefore, apply variable rate fertilisers.

Mapping Particle Size and Soil Organic Matter in Tropical Soil Based on Hyperspectral Imaging and Non-Imaging Sensors

open access: yesRemote Sensing, 2021
We evaluated the use of airborne hyperspectral imaging and non-imaging sensors in the Vis—NIR—SWIR spectral region to assess particle size and soil organic matter in the surface layer of tropical soils (Oxisols, Ultisols, Entisols).

The Sense of Proximity [PDF]

open access: yesNature, 1909
IN NATURE for March 11 there is an interesting account by Dr. McKendrick of some investigations by Kunz, of Mulhausen, and Prof. Griesbach, on the senses of the blind. Among other points that he refers to and discusses is the question of the ability of the blind to avoid obstacles and find their way about.

Proximity sensing with wavelet-generated video [PDF]

open access: yesJournal of Electronic Imaging, 1998
Abstract : In this paper we introduce wavelet video processing of proximity sensor signals. Proximity sensing is required for a wide range of military and commercial applications, including weapon fuzing, robotics, and automotive collision avoidance.

In-Orchard Sizing of Mango Fruit: 1. Comparison of Machine Vision Based Methods for On-The-Go Estimation

open access: yesHorticulturae, 2022
Estimation of fruit size on-tree is useful for yield estimation, harvest timing and market planning. Automation of measurement of fruit size on-tree is possible using RGB-depth (RGB-D) cameras, if partly occluded fruit can be removed from consideration ...
