Special Issue Information

Dear Colleagues,

Facing climate change and an increasing population, the reduced supply of agronomic inputs and the rational exploitation of natural resources should be reconciled with high production standards and farmer income. In this context, the use of remote-sensing tools (platform and sensors) such as satellites plays a fundamental role.

With the aim of introducing cutting-edge satellite applications to the scientific community, I am pleased to invite you to submit your work to this Special Issue, “Use of Satellite Imagery in Agriculture—Volume II”. Papers may be original research articles and reviews regarding the use of optical and radar satellite images for precision agriculture applications and the sustainable development of agronomy. In particular, research areas may include (but are not limited to) the following: spatio-temporal variability in cropping systems, retrieval of soil properties, crop monitoring (e.g., phenology and stress), yield prediction, and crop recognition using artificial intelligence. Papers addressing satellite time series, data fusion, or collecting in situ data are also welcome, as well as those using a combination of remote-sensing tools where satellites represent the leading platform.

I look forward to receiving your contributions.

Combining Gaussian Process Regression with Poisson Blending for Seamless Cloud Removal from Optical Remote Sensing Imagery for Cropland Monitoring

Abstract

Constructing optical image time series for cropland monitoring requires a cloud removal method that accurately restores cloud regions and eliminates discontinuity around cloud boundaries. This paper describes a two-stage hybrid machine learning-based cloud removal method that combines Gaussian process regression (GPR)-based predictions with image blending for seamless optical image reconstruction. GPR is employed in the first stage to generate initial prediction results by quantifying temporal relationships between multi-temporal images. GPR predictive uncertainty is particularly combined with prediction values to utilize uncertainty-weighted predictions as the input for the next stage. In the second stage, Poisson blending is applied to eliminate discontinuity in GPR-based predictions. The benefits of this method are illustrated through cloud removal experiments using Sentinel-2 images with synthetic cloud masks over two cropland sites. The proposed method was able to maintain the structural features and quality of the underlying reflectance in cloud regions and outperformed two existing hybrid cloud removal methods for all spectral bands. Furthermore, it demonstrated the best performance in predicting several vegetation indices in cloud regions. These experimental results indicate the benefits of the proposed cloud removal method for reconstructing cloud-contaminated optical imagery. Full article
