Special Issue Information

Dear Colleagues,

Thermography non-destructive testing is an overarching field of research focusing on the physics–mathematical foundations and practical applications of thermography NDT and its multi-excitation, interpretation, system, signal processing and artificial intelligent algorithms that learn, reason and act. It bridges the boundary between theory and application, developing novel theoretically inspired methodologies targeting both longstanding and emergent thermography-based NDT methods and applications. The core of thermography lies in its use of and proposed physic meaning in various thermography NDT, physically guided AI methodologies combined with convex and non-convex optimization of machine learning/deep learning neural networks. The novel developments in these areas specialised to the processing of a variety of modalities include infrastructure, chemical, bio area, multi-physics signals, images, multispectral, and video, among others.

The focus of the Special Issue will be on a broad range of sensors, physic interpretation, signal and artificial intelligent processing involving the introduction and development of new advanced theoretical and practical algorithms.

Potential topics include but are not limited to the following:

  • Induction, optical, laser, ultrasound, and flash thermography NDT;
  • Multimodality excitation, such as lock in, pulsed, step heating, etc.;
  • Physical guided thermography processing and machine learning;
  • Different thermography NDT applications;
  • Computer vision and 3D reconstruction by multimodal sensor data fusion;
  • Fusion of thermography NDT with other NDT methods;
  • Non-destructive testing and evaluation and structure health monitoring for material characterization, structural integrity, defect detection and identification, stress and lifecycle assessment.

This study presents a novel method for the nighttime detection of waterborne individuals using an enhanced YOLOv5s algorithm tailored for infrared thermal imaging. To address the unique challenges of nighttime water rescue operations, we have constructed a specialized dataset comprising 5736 thermal images collected from diverse aquatic environments. This dataset was further expanded through synthetic image generation using CycleGAN and a newly developed color gamut transformation technique, which significantly improves the data variance and model training effectiveness. Furthermore, we integrated the Convolutional Block Attention Module (CBAM) at the end of the last encoder’s feedforward network. This integration maximizes the utilization of channel and spatial information to capture more intricate details in the feature maps. To decrease the computational demands of the network while maintaining model accuracy, Ghost convolution was employed, thereby boosting the inference speed as much as possible. Additionally, we applied hyperparameter evolution to refine the training parameters. The improved algorithm achieved an average detection accuracy of 85.49% on our proprietary dataset, significantly outperforming its predecessor, with a prediction speed of 23.51 FPS. The experimental outcomes demonstrate the proposed solution’s high recognition capabilities and robustness, fulfilling the demands of intelligent lifesaving missions. Full article
