Special Issue Information

Dear Colleagues,

The environmental and socioeconomic impacts of climate change have been become increasingly apparent, affecting different aspects of human life. To deal with such a global problem, many countries and multinational companies have committed to several environmental pledges, most notably the one to achieve net-zero carbon by 2040. However, it is not easy to monitor and manage progress without the aid of modern technologies. In particular, advances in high-altitude imaging have facilitated the capture of large-scale image datasets, thus benefiting the development of data-driven environmental remote sensing research. In addition to the abundant data now available, the growing interest in deep unfolding techniques is also essential to further developing this field. Efficient and interpretable deep learning approaches provide new insights into the monitoring and management of environmental footprint, signifying their importance in environmental remote sensing research.

This Special Issue aims to specify and summarizes current challenges, innovations, and achievements in environmental remote sensing research. This type of research agenda is essential to facilitate efficient and interpretable deep learning in future studies. Additionally, it fits well with the journal scope of image processing and computer vision.

Three important aspects will be covered: challenges, innovations, and achievements in deep learning in environmental remote sensing. Submissions to the Special Issue can thus be categorized as follows:

  • Surveys and short communications that deal with a small aspect, such as a specific challenge or idea, without details about its implementation or verification.
  • Original research articles that present novel solutions to existing challenges and provide details about their implementation and verification.
  • Systematic review articles that collate studies in the literature and provide a comprehensive description of achievements. They should also specify current difficulties and discuss future research directions.

Crack inspection is important to monitor the structural health of pavement structures and make the repair process easier. Currently, pavement crack inspection is conducted manually, which is inefficient and costly at the same time. To solve the problem, this work has developed a robotic system for automated data collection and analysis in real-time. The robotic system navigates the pavement and collects visual images from the surface. A deep-learning-based semantic segmentation framework named RCDNet was proposed. The RCDNet was implemented on the onboard computer of the robot to identify cracks from the visual images. The encoder-decoder architecture was utilized as the base framework of the proposed RCDNet. The RCDNet comprises a dual-channel encoder and a decoder module. The encoder and decoder parts contain a context-embedded channel attention (CECA) module and a global attention module (GAM), respectively. Simulation results show that the deep learning model obtained 96.29% accuracy for predicting the images. The proposed robotic system was tested in both indoor and outdoor environments. The robot was observed to complete the inspection of a 3 m × 2 m grid within 10 min and a 2.5 m × 1 m grid within 6 min. This outcome shows that the proposed robotic method can drastically reduce the time of manual inspection. Furthermore, a severity map was generated using the visual image results. This map highlights areas that require greater attention for repair in the test grid. Full article

Cracks in concrete surfaces are one of the most prominent causes of the degradation of concrete structures such as bridges, roads, buildings, etc. Hence, it is very crucial to detect cracks at an early stage to inspect the structural health of the concrete structure. To solve the drawbacks of manual inspection, Image Processing Techniques (IPTs), especially those based on Deep Learning (DL) methods, have been investigated for the past few years. Due to the groundbreaking development of this field, researchers have devoted their endeavors to detecting cracks using DL-based IPTs and as a result, the techniques have given answers to many challenging problems. However, to the best of our knowledge, a state-of-the-art systematic review paper is lacking in this field that would present a scientometric analysis as well as a critical survey of the existing works to document the research trends and summarize the prominent IPTs for detecting cracks in concrete structures. Therefore, this article comes forward to spur researchers with a systematic review of the relevant literature, which will present both scientometric and critical analysis of the papers published in this research area. The scientometric data that are brought out from the articles are analyzed and visualized by using VOSviewer and CiteSpace text mining tools in terms of some parameters. Furthermore, this article elucidates research from all over the world by highlighting and critically analyzing the incarnated essence of some of the most influential papers. Moreover, this research raises some common questions as well as extracts answers from the analyzed papers to highlight various features of the utilized methods. Full article
