Abstract:

Image Quality Assessment (IQA) is a valuable and vital research topic in image processing and computer vision, aiming to construct image quality assessment models in accordance with human visual perception. With the rapid advancement of Artificial Intelligence-Generated Content (AIGC), remarkable progress has been made in visual generation, particularly in image synthesis. However, due to the inherent limitations of image generation mechanisms, Artificial Intelligence-Generated Images (AIGI) often exhibit various quality defects, including semantic drift, unreasonable structures, and visual artifacts. Traditional IQA methods fail to adequately capture these unique defects, thus falling short in meeting the evaluation needs for AIGI. Consequently, AIGI Quality Assessment (AIGIQA) has emerged as a prominent research topic in computer vision. Existing technical frameworks and research methodologies of AIGIQA were comprehensively reviewed, systematically investigated, and thoroughly analyzed. First, three representative image generation paradigms, namely generative adversarial networks, autoregressive models, and diffusion models, were reviewed, and the typical image quality defects associated with different generation mechanisms were analyzed. Next, the quality evaluation dimensions of AIGI were summarized from five perspectives, including technical issues, AI artifacts, unnaturalness, discrepancy, and aesthetics. Furthermore, commonly used performance evaluation metrics for AIGIQA models were reviewed, and publicly available datasets were introduced and compared. In addition, the development of traditional IQA methods was revisited, and their limitations in assessing AIGI were thoroughly discussed. Existing AIGIQA approaches were further categorized, with particular emphasis on the technical frameworks, core ideas, and limitations of representative methods based on cross-modal alignment and Multimodal Large Language Models (MLLMs). Finally, the opportunities and challenges faced by AIGIQA in quality representation, dataset support, model construction, and interpretability were discussed, and potential directions for future research were identified, providing valuable references for subsequent studies in this field.
