Special Issue Information

Dear Colleagues,

Machine vision and hyperspectral imaging are two related sets of technologies that have been extensively developed and successfully applied in the agri-food sector over the last few years. In the last decade, these technologies have undergone a remarkable evolution with the availability of better imaging sensors and increased computational power.

These technologies are capable at efficiently and non-destructively measuring the quality and safety of agricultural products and have recently achieved great success in the agri-food sector, helping farmers make informed decisions and optimizing crop management.

Their application is expected to continue growing in line with artificial intelligence and deep learning algorithms that are being developed within these frameworks and has recently achieved great success in conventional techniques.

This Special Issue aims to present the latest advances in machine vision and hyperspectral imaging techniques and their contributions to a wide range of applications in the agri-food sector, enabling us to foresee where they will lead the sector and its practices in the coming years.

Dr. Pedro Couto
Guest Editor

Almond cultivation is of great socio-economic importance worldwide. With the demand for almonds steadily increasing due to their nutritional value and versatility, optimizing the management of almond orchards becomes crucial to promote sustainable agriculture and ensure food security. The present systematic literature review, conducted according to the PRISMA protocol, is devoted to the applications of remote sensing technologies in almond orchards, a relatively new field of research. The study includes 82 articles published between 2010 and 2023 and provides insights into the predominant remote sensing applications, geographical distribution, and platforms and sensors used. The analysis shows that water management has a pivotal focus regarding the remote sensing application of almond crops, with 34 studies dedicated to this subject. This is followed by image classification, which was covered in 14 studies. Other applications studied include tree segmentation and parameter extraction, health monitoring and disease detection, and other types of applications. Geographically, the United States of America (USA), Australia and Spain, the top 3 world almond producers, are also the countries with the most contributions, spanning all the applications covered in the review. Other studies come from Portugal, Iran, Ecuador, Israel, Turkey, Romania, Greece, and Egypt. The USA and Spain lead water management studies, accounting for 23% and 13% of the total, respectively. As far as remote sensing platforms are concerned, satellites are the most widespread, accounting for 46% of the studies analyzed. Unmanned aerial vehicles follow as the second most used platform with 32% of studies, while manned aerial vehicle platforms are the least common with 22%. This up-to-date snapshot of remote sensing applications in almond orchards provides valuable insights for researchers and practitioners, identifying knowledge gaps that may guide future studies and contribute to the sustainability and optimization of almond crop management.
