Automatic Image Captioning

The use of computer vision and machine learning algorithms to automatically generate textual descriptions of images without human intervention. Social media platforms like Facebook and Instagram deploy automatic image captioning to provide alternative text for user-uploaded photos, identifying elements such as objects, people, text, and scenes. While these systems can operate at massive scale and provide some level of access for screen reader users, they are frequently criticized for lacking contextual information, missing the author's intent, and producing generic or inaccurate descriptions that can mislead users. Best practice recommends hybrid approaches that combine machine-generated descriptions with human editing to balance scalability with quality.
