Multimodal Image Content Embedding and Vector Search Workflow
Key Features and Highlights
This workflow enables downloading images from Google Drive, automatically extracting color channel information and semantic keywords from images, and leveraging a multimodal large language model (OpenAI vision model) to generate descriptive text. The extracted information is then integrated into embedding documents and stored in an in-memory vector database, supporting vector-based image search via text prompts. A key highlight is the combination of image editing nodes and advanced AI models to achieve automatic semantic representation and efficient retrieval of image content.
Core Problems Addressed
Traditional image search relies heavily on tags or manual annotations, resulting in low efficiency and limited accuracy. This workflow addresses these challenges by automatically extracting color information and semantic keywords from images to generate structured embedding documents. It solves the problem of intelligent image content representation and semantic-based vector retrieval, thereby enhancing the intelligence level of image management and search.
