Special Issue Information

Dear Colleagues,

In recent years, we have witnessed remarkable success in machine learning across various research areas and applications, including natural language processing, healthcare, wide-area surveillance, network security, and precision agriculture. In particular, the field of image analysis has been significantly impacted by deep learning techniques, which have revolutionized image classification by enabling unprecedented accuracy and efficiency. However, challenges still persist in image analytics and interpretation, calling for more advanced computational methods.

The purpose of this Special Issue is to explore the latest advancements in algorithms, architectures, and methodologies that have pushed image classification into new realms of possibility. We aim to go beyond existing machine learning approaches and delve into topics such as deep learning innovations, transfer learning applications, and the integration of unsupervised and semi-supervised learning. By doing so, we not only strive to enhance classification performance but also address issues of interpretability, scalability, and real-world applicability.

We invite researchers, practitioners, and enthusiasts in the field to contribute their insights and findings to this Special Issue. Your contributions will play a pivotal role in shaping the future of image classification and machine learning as a whole. We encourage submissions that explore theoretical frameworks, practical implementations, and interdisciplinary approaches. Through this collective effort, we aim to foster a fruitful exchange of ideas that will inspire further innovation and collaboration.

Thank you for considering this opportunity to promote your work in this exciting domain. We hope to receive your submissions and embark on this journey of exploration and discovery. The objective of this Special Issue is to provide a forum for cutting-edge research that tackles the ongoing challenges in image classification. We welcome topics that include, but are not limited to, the following areas:

  • Deep learning innovations in image classification;
  • Transfer learning applications for image analysis;

Breast cancer is recognized as an aggressive cancer with the highest rate of mortality. Ultrasound imaging is a non-invasive and cost-effective strategy which is most frequently utilized in clinical methods. Especially, in ultrasound scan, breast tumors may appear in blurred and unclear boundaries. Thus, there is a necessity to improve the quality of breast ultrasound images. In this work, we introduce a cycle generative adversarial network (GAN) for translating noisy breast ultrasound images to denoised images. Furthermore, translating denoised images to reconstructed images helps in preserving breast tumor boundaries for better efficacy. To accurately identify the augmented breast tumor images, we consider an ensemble model of pre-trained transfer learning models such as Inception-v3, Densenet121, and XceptionLike. Furthermore, we present an automated boundary extraction using Local Interpretable Model-agnostic Explanations (LIME), providing interpretability for boundary extraction in breast lesions from ultrasound images. Through experimentation, we have achieved 93% of accuracy for the proposed model, and LIME provides better interpretability for each pre-trained model. Furthermore, the proposed model outperforms Vison Transformer (ViT) models. Full article

Over the past few years, the rapid development of deepfake technology based on generative models has posed a significant threat to the field of information security. Despite the notable progress in deepfake-detection methods based on the spatial domain, the detection capability of the models drops sharply when dealing with low-quality images. Moreover, the effectiveness of detection relies on the realism of the forged images and the specific traces inherent to particular forgery techniques, which often weakens the models’ generalization ability. To address this issue, we propose the Frequency-Domain Masking and Spatial Interaction (FMSI) model. The FMSI model innovatively introduces masked image modeling in frequency-domain processing. This prevents the model from focusing too much on specific frequency-domain features and enhances its generalization ability. We design a high-frequency information convolution module for spatial and channel dimensions to help the model capture subtle forgery traces more effectively. Also, we creatively design a dual stream architecture for frequency-domain and spatial-domain information interaction and overcome single-domain detection limitations. Our model is tested on three public benchmark datasets (FaceForensics++, Celeb-DF, and WildDeepfake) through intra-domain and cross-domain experiments. The detection and generalization capabilities of the model are evaluated using the AUC and EER metrics. The experimental results demonstrate that our model not only possesses high detection capability but also exhibits excellent generalization ability. Full article
