Alt Text

Alternative text (alt text) provides textual descriptions of images for users with visual impairments, improving accessibility. Current research focuses on automatically generating accurate and contextually relevant alt text using multimodal deep learning models that leverage both image content and surrounding textual information, addressing limitations of simpler methods. These advancements aim to improve the accessibility of online content and are evaluated using both automated metrics and human assessments, highlighting the need for context-aware evaluation methods. The development of robust and efficient alt text generation systems has significant implications for digital accessibility and inclusivity.
