Special Issue Information

Dear Colleagues,

The field of computer vision has undergone a significant transformation with the advent of deep learning techniques, enabling the development of innovative applications across various domains. This Special Issue focuses on exploring the latest advancements, methodologies, and applications in this rapidly evolving area.

Deep learning methods, such as convolutional neural networks (CNNs), vision transformer (ViT), diffusion models and generative adversarial networks (GANs), have demonstrated remarkable success in tasks such as object recognition, semantic segmentation and image synthesis. These techniques have paved the way for a myriad of applications, including autonomous vehicles, facial recognition, biomedical image analysis and video surveillance, among others.

We invite contributions that present cutting-edge research, novel techniques, methods, tools and ideas related to the integration of deep learning in computer vision. Submissions may cover a wide range of topics, including, but not limited to:

  • Advances in deep learning architectures for computer vision tasks;
  • Transfer learning and domain adaptation in computer vision;
  • Deep reinforcement learning for vision-based control;
  • Generative models for image synthesis and manipulation;
  • Application of computer vision technology in biomedical imaging;
  • Applications of deep learning in fields such as remote sensing, robotics and art.

We encourage submissions that propose innovative and scientifically grounded research lines for the future development of deep learning techniques in computer vision. Together, we aim to advance the field of computer vision and its applications in various industries.

Training a model to recognize human actions in videos is computationally intensive. While modern strategies employ transfer learning methods to make the process more efficient, they still face challenges regarding flexibility and efficiency. Existing solutions are limited in functionality and rely heavily on pretrained architectures, which can restrict their applicability to diverse scenarios. Our work explores knowledge distillation (KD) for enhancing the training of self-supervised video models in three aspects: improving classification accuracy, accelerating model convergence, and increasing model flexibility under regular and limited-data scenarios. We tested our method on the UCF101 dataset using differently balanced proportions: 100%, 50%, 25%, and 2%. We found that using knowledge distillation to guide the model’s training outperforms traditional training without affecting the classification accuracy and while reducing the convergence rate of model training in standard settings and a data-scarce environment. Additionally, knowledge distillation enables cross-architecture flexibility, allowing model customization for various applications: from resource-limited to high-performance scenarios. Full article

The application of large field-of-view (FoV) cameras equipped with fish-eye lenses brings notable advantages to various real-world computer vision applications, including autonomous driving. While deep learning has proven successful in conventional computer vision applications using regular perspective images, its potential in fish-eye camera contexts remains largely unexplored due to limited datasets for fully supervised learning. Semi-supervised learning comes as a potential solution to manage this challenge. In this study, we explore and benchmark two popular semi-supervised methods from the perspective image domain for fish-eye image segmentation. We further introduce FishSegSSL, a novel fish-eye image segmentation framework featuring three semi-supervised components: pseudo-label filtering, dynamic confidence thresholding, and robust strong augmentation. Evaluation on the WoodScape dataset, collected from vehicle-mounted fish-eye cameras, demonstrates that our proposed method enhances the model’s performance by up to 10.49% over fully supervised methods using the same amount of labeled data. Our method also improves the existing image segmentation methods by 2.34%. To the best of our knowledge, this is the first work on semi-supervised semantic segmentation on fish-eye images. Additionally, we conduct a comprehensive ablation study and sensitivity analysis to showcase the efficacy of each proposed method in this research. Full article
