STRESS MONITORING OF MULBERRY PLANTS BY FINDING REP USING HYPERSPECTRAL DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Stressed on crop can be monitored using different indices. Red Edge position is good estimator for stress monitoring. The red edge position (REP) is strongly correlated with foliar chlorophyll content.

Study on red edge characteristics of rice spectral caused by nitrogen level

open access: yes浙江大学学报. 农业与生命科学版, 2001
The canopy spectra of rice under different nitrogen levels were studied. Some red edge parameters in the first derivative reflectance curve (wavelength, amplitude and area of the red edge peak) were studied to evaluate rice leaf chlorophyll, LAI etc. Red

Assessing rice blast disease severity through hyperspectral remote sensing

open access: yesJournal of Agrometeorology, 2022
Remote sensing is being increasingly used in stress management in different agricultural practices. It is useful for real time analysis for crop stress which is not possible for visual observation alone. Rice blast caused by fungus Pyricularia Oryzae is

K-Edge Structure in Shock-Compressed Chlorinated Parylene

open access: yesAtoms, 2023
We have carried out a series of experiments to measure the Cl K-absorption edge for shock-compressed samples of chlorinated parylene. Colliding shocks allowed us to compress samples up to four times the initial density with temperatures up to 10 eV.

Decision-Based Demosaicking Algorithm Using Bayesian Theorem

open access: yesIEEE Access, 2018
In this paper, we introduce a new color filter array interpolation based on edge map prediction using the Bayesian theorem. The edge information obtained at the position of the green component sampled in the quincunx grid using the Bayer pattern is used ...

A New Method for Estimating Soil Fertility Using Extreme Gradient Boosting and a Backpropagation Neural Network

open access: yesRemote Sensing, 2022
Soil fertility affects crop yield and quality. A quick, accurate evaluation of soil fertility is crucial for agricultural production. Few satellite image-based evaluation studies have quantified soil fertility during the crop growth period.

Remote Sensing Monitoring of Rice Fields: Towards Assessing Water Saving Irrigation Management Practices

open access: yesFrontiers in Remote Sensing, 2021
Rice cultivation is one of the largest users of the world’s freshwater resources. The contribution of remote sensing observations for identifying the conditions under which rice is cultivated, particularly throughout the growing season, can be ...
