AI-Powered UK Passport Photo Validator
detail.loadingPreview
This workflow automates the validation of portrait photos against the strict UK government guidelines for passport photos using an AI vision model. It downloads images, resizes them, and then leverages AI to assess compliance, providing structured feedback on validity and reasons for rejection.
About This Workflow
This powerful n8n workflow streamlines the process of verifying passport photo suitability. It begins by importing photos, exemplified here from Google Drive, though easily adaptable to other sources. Each image is then pre-processed—resized to optimal dimensions—before being fed into an AI vision model. Crucially, the AI is prompted with the comprehensive UK government passport photo guidelines, ensuring accurate and compliant assessments. The final step uses a structured output parser to transform the AI's natural language response into a clear, actionable JSON object, indicating validity, descriptive details, and specific reasons for non-compliance.
Key Features
- AI-Driven Compliance: Automatically validate photos against specific UK government passport photo guidelines using an integrated AI vision model.
- Flexible Image Ingestion: Easily adapt to various photo sources, demonstrated with Google Drive integration, for seamless image import.
- Automated Image Preparation: Includes image resizing to optimize photos for AI processing, ensuring consistent and efficient analysis.
- Structured AI Feedback: Parses AI responses into a clear, actionable JSON format, including
is_validstatus,photo_description, and detailedreasonsfor non-compliance. - Scalable Validation: Process multiple photos in batches, making it ideal for photo studios, travel agencies, or online submission platforms.
How To Use
- Trigger the Workflow: Start the workflow by clicking 'Test workflow' in the 'When clicking ‘Test workflow’' node.
- Configure Photo Sources: Modify the 'Photo URLs' node to input your image URLs. The current setup uses Google Drive links; replace these with your desired photo sources or integrate a different trigger (e.g., a webhook for new uploads).
- Set Up Google Drive Credentials (if using): Ensure the 'Download Photos' node has valid Google Drive credentials configured to access your images.
- Review AI Guidelines: The 'Passport Photo Validator' node contains the specific UK government passport photo guidelines. Review these to ensure they align with any updated regulations or if you wish to adapt for other countries.
- Utilize Structured Output: The 'Structured Output Parser' node provides a clear JSON output (
is_valid,photo_description,reasons). Connect this to your next node to update databases, send notifications, or further process the validation results.
