Special Issue Information

Dear Colleagues,

Object detection in remote sensing images plays a crucial role in various fields, such as urban planning, land cover classification, disaster management, and environmental monitoring. 

The importance of object detection lies in its ability to extract valuable information from remote sensing data, enabling better decision making and analysis. By accurately identifying and delineating objects, it becomes possible to monitor changes over time, assess the impact of natural disasters, detect illegal activities, and plan for infrastructure development. Additionally, object detection aids in the creation of detailed land cover maps, which are essential for urban growth modeling, precision agriculture, and conservation efforts.

However, object detection in remote sensing images also presents several challenges. These include the presence of complex backgrounds and variations in object appearances due to different imaging conditions, scale differences, and occlusions caused by vegetation or other objects. Furthermore, the large size of remote sensing datasets requires efficient algorithms capable of handling big data.

The aim of this Special Issue is to collate original research as well as review articles on the subject of object detection in remote sensing images. Potential topics include, but are not limited to, the following: 

  • Object detection;
  • Remote sensing images;
  • Urban planning;
  • Environmental monitoring;
  • Disaster management;
  • Deep learning;
  • Mapping;
  • Real-time detection.

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. Journal of Imaging is an international peer-reviewed open access monthly 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 1800 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.

Forest damage has become more frequent in Hungary in the last decades, and remote sensing offers a powerful tool for monitoring them rapidly and cost-effectively. A combined approach was developed to utilise high-resolution ESA Sentinel-2 satellite imagery and Google Earth Engine cloud computing and field-based forest inventory data. Maps and charts were derived from vegetation indices (NDVI and Z∙NDVI) of satellite images to detect forest disturbances in the Hungarian study site for the period of 2017–2020. The NDVI maps were classified to reveal forest disturbances, and the cloud-based method successfully showed drought and frost damage in the oak-dominated Nagyerdő forest of Debrecen. Differences in the reactions to damage between tree species were visible on the index maps; therefore, a random forest machine learning classifier was applied to show the spatial distribution of dominant species. An accuracy assessment was accomplished with confusion matrices that compared classified index maps to field-surveyed data, demonstrating 99.1% producer, 71% user, and 71% total accuracies for forest damage and 81.9% for tree species. Based on the results of this study and the resilience of Google Earth Engine, the presented method has the potential to be extended to monitor all of Hungary in a faster, more accurate way using systematically collected field-data, the latest satellite imagery, and artificial intelligence.
