Extract and Validate Book Titles from Bookshelf Images Using GPT-4o and Google Books

This workflow is designed to handle images containing multiple book spines, such as those from a bookshelf. It leverages AI to extract readable book titles and authors from the image, ensuring accuracy by querying Google Books for validation. The process involves normalizing input data, analyzing the image, splitting the extracted data for individual validation, and finally reaggregating the validated list for output. This ensures that only accurate and deduplicated book information is returned to the user.
