Dear Colleagues,
The use of red, green, and blue (RGB) color imaging can provide a wide range of crop monitoring and plant phenotyping applications, with their utility in application depending basically on the reliability of the algorithms implemented. This is one of the reasons why a low-cost sensor, such as a color digital (RGB) camera, is being included more and more as a key component in the most advanced platforms, whether under controlled or field conditions. In the latter case, RGB cameras can be installed in portable platforms on the ground, from a mobile phone mounted on a pole to sophisticated multisensor platforms, or used aerially (e.g., mounted on unmanned or manned aerial platforms, from drones to aircraft to satellites).
Besides the formulation of vegetation indices, RGB images are amenable for assessing a wide range of other traits, even in the field, such as counting agronomical yield components, assessing phenological stages, conducting regular monitoring of crop development, measuring the growth of individual plants, and identifying foliar symptoms associated to a myriad of biotic and abiotic stresses. This is due to the wide versatility of the data collected by RGB cameras, which is essentially linked to the high resolution of these images and the general high quality of factory color calibration. Other than the appropriate software (to run the specific algorithms), and the use of advanced statistical and modeling approaches, including deep learning, machine learning, and artificial intelligence, which are all developing quickly, the other main limitation is the need for high-performance computing capable of applying results in real-time. Solving that point may pave the way for a wide number of applications to be implemented based on the interpretation and use of RGB images alone.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
