Transfer-learning-based approach for leaf chlorophyll content estimation of winter wheat from hyperspectral data
TL;DR: In this paper, the authors proposed a novel hybrid method, which is based on the combination of amplitude and shape-enhanced 2D correlation spectrum (2DCOS) and transfer learning.

UAV-based chlorophyll content estimation by evaluating vegetation index responses under different crop coverages
TL;DR: In this article , a UAV carrying multispectral sensor was used to collect visible and near-infrared images of the canopy at the jointing stage of maize under six fertilization levels to obtain VIs.

Improving estimation of LAI dynamic by fusion of morphological and vegetation indices based on UAV imagery
TL;DR: In this paper , the authors explored the potential of fusion of morphological information and spectral information in multiple growth periods of maize to improve the accuracy of leaf area index (LAI) dynamic estimation.

Eliminating the interference of soil moisture and particle size on predicting soil total nitrogen content using a NIRS-based portable detector
TL;DR: A NIRS-based portable detector of soil TN content was developed that measures spectral data at 940, 1050, 1100, 1200, 1300, 1450, and 1550nm and an algorithm was proposed to normalize the original spectral data into the standard spectral data and eliminate the interference of soil moisture.

Estimation of Chlorophyll Content in Potato Leaves Based on Spectral Red Edge Position
TL;DR: In this paper, hyperspectral images of 65 potato leaves were collected and divided into 400 regions of interesting (ROI), while the SPAD values of these 400 ROI samples were measured.
