Special Issue Information

Dear Colleagues,

Due to the positive response from the researchers in the related domain regarding the Special Issue “Deep Learning Techniques for Forest Parameter Retrieval and Accurate Tree Modeling from Remote Sensing Data” belonging to the Journal of Forests, the succession of the second volume of this Special Issue with the same theme is set out herein to collect related manuscripts that convey the latest technologies applied in forestry. The original Special Issue of Volume I has been permanently closed.

Deep learning and digital twin technologies have the potential to retrieve forest parameters and simulate the forest life cycle, which is beneficial for forest silvicultural management and tree phenotypic trait characterization. While the foundations of these technologies have been laid through proof-of-concept studies, we can now make transformative advances, especially in forest studies.

In this issue, we welcome all studies which deploy deep learning technologies and digital twin techniques in forestry applications. We intend to cover some aspects, including various remote sensing data analysis, deep learning method developments, significant issue remedies and forest scenario rendering, along with inspiring and heuristic concepts in the multidisciplinary field that promote implementing technologies into forestry.

Specific topics include, but are not limited to:

  • The demonstration of deep learning methodologies for processing forest remote sensing data;
  • Software approaches to forest visualization and modeling;
  • A comparison between deep learning methods and other algorithms in a forest survey;
  • Forest scenario reconstruction from LiDAR data or other remote sensing data;
  • Virtual forest management based on virtual reality technology;
  • Computer graphics or machine vision algorithms that enhance the fidelity of reproduced forest environments;
  • The prediction of variations in forest growth properties based on deep learning frameworks from remote sensing data;
  • The application of multi-remote sensing data in combination with deep learning frameworks for forestry carbon sink measurements;
  • Processing terminal forest data acquired from various peripherals using deep learning approaches.

Abstract
The leaf area index (LAI) is an essential indicator for assessing vegetation growth and understanding the dynamics of forest ecosystems and is defined as the ratio of the total leaf surface area in the plant canopy to the corresponding surface area below it. [...] Read more.
The leaf area index (LAI) is an essential indicator for assessing vegetation growth and understanding the dynamics of forest ecosystems and is defined as the ratio of the total leaf surface area in the plant canopy to the corresponding surface area below it. LAI has applications for obtaining information on plant health, carbon cycling, and forest ecosystems. Due to their price and portability, mobile devices are becoming an alternative to measuring LAI. In this research, a new method for estimating LAI using a smart device with a fisheye lens (SFL) is proposed. The traditional Otsu method was enhanced to improve the accuracy and efficiency of foreground segmentation. The experimental samples were located in Gansu Ziwuling National Forest Park in Qingyang. In the accuracy parameter improvement experiment, the variance of the average LAI value obtained by using both zenith angle segmentation and azimuth angle segmentation methods was reduced by 50%. The results show that the segmentation of the front and back scenes of the new Otsu method is more accurate, and the obtained LAI values are more reliable. In the efficiency parameter improvement experiment, the time spent is reduced by 17.85% when the enhanced Otsu method is used to ensure that the data anomaly rate does not exceed 10%, which improves the integration of the algorithm into mobile devices and the efficiency of obtaining LAI. This study provides a fast and effective method for the near-ground measurement of forest vegetation productivity and provides help for the calculation of forest carbon sequestration efficiency, oxygen release rate, and forest water and soil conservation ability.
