Special Issue Information

Dear Colleagues,

In AI and machine learning-based image processing, symmetry and asymmetry are fundamental properties that significantly impact pattern recognition, feature extraction, and algorithmic performance. This Special Issue, "Symmetry and Asymmetry in Artificial Intelligence and Machine Learning-Based Image Processing", explores how these properties can enhance modern computational imaging systems.

We welcome innovative research contributions that advance our understanding of how AI and ML algorithms can effectively leverage symmetrical and asymmetrical patterns encompassing both theoretical frameworks and practical applications.

Of particular interest are cutting-edge approaches to symmetry detection, asymmetric pattern recognition, and their real-world applications across diverse domains, including medical imaging, autonomous driving, computer vision, and industrial automation. We seek submissions that demonstrate how symmetry and asymmetry principles can improve the robustness, efficiency, and performance of AI-driven image processing solutions.

We invite original research articles, comprehensive reviews, and case studies that explore novel methodologies, theoretical advances, or practical implementations. Submissions may emphasize how symmetry/asymmetry considerations can advance the state-of-the-art in AI and ML-based image processing.

Diffusion models, as representative models in the field of artificial intelligence, have made significant progress in text-to-image synthesis. However, studies of style transfer using diffusion models typically require a large amount of text to describe semantic content or specific painting attributes, and the style and layout of semantic content in synthesized images are frequently uncertain. To accomplish high-quality fixed content style transfer, this paper adopts text-free guidance and proposes a multi-source, training-free and controllable style transfer method by using single image or video as content input and single or multiple style images as style guidance. To be specific, the proposed method firstly fuses the inversion noise of a content image with that of a single or multiple style images as the initial noise of stylized image sampling process. Then, the proposed method extracts the self-attention mechanism’s query, key, and value vectors from the DDIM inversion process of content and style images and injects them into the stylized image sampling process to improve the color, texture and semantics of stylized images. By setting the hyperparameters involved in the proposed method, the style transfer effect of symmetric style proportion and asymmetric style distribution can be achieved. By comparing with state-of-the-art baselines, the proposed method demonstrates high fidelity and excellent stylized performance, and can be applied to numerous image or video style transfer tasks.
