Multimodal Image Retrieval Through Iterative Semantic Refinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image retrieval systems rely on keyword-based and visual similarity techniques that fail to understand the context and nuanced meanings of complex, ambiguous, or multi-meaning queries, requiring extensive manual labeling and struggling with diverse and dynamic data landscapes.
Innovation Solution
A system utilizing a vision-language model for semantic analysis, which identifies semantic concepts from an input query, retrieves images based on these concepts, and iteratively refines the search through user interaction and domain expert feedback, incorporating a tokenizer to compare images against a predefined label space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional keyword-based approaches are used for text and visual similarity techniques for images, then the system is simple to implement, but it cannot understand context, meaning, or intent behind user queries
Solution Approach 1:
The patent introduces vision-language models and tokenizer as intermediary components that bridge the gap between simple keyword matching and deep semantic understanding. These intermediaries translate images and queries into semantic representations that capture context and meaning without requiring full complex analysis of all image content.
Solution Approach 2:
The system segments the image analysis task by using a tokenizer to identify and extract only the relevant concepts from images, rather than analyzing entire images or all possible features. This segmentation allows the system to focus on semantically important elements while maintaining simplicity.
2Measurement precision
If extensive accurately labeled datasets are used to train models, then the search and retrieval effectiveness is improved, but substantial manual labor is required to create and maintain these datasets
Solution Approach 1:
The system employs vision-language models that can automatically generate semantic annotations and concepts from images without requiring manual labeling. The models self-service by extracting relevant concepts and creating training data automatically, reducing the need for human annotators while maintaining high search accuracy.
3Loss of information
If conventional visual similarity techniques are used for image retrieval, then the retrieval process is fast, but it limits the ability to understand deeper semantic content or thematic connections between images
Solution Approach 1:
The system performs preliminary action by pre-processing images to extract and store relevant semantic concepts and features before retrieval. This preliminary extraction of key concepts allows the system to maintain fast retrieval speeds while capturing deeper semantic content, as the heavy lifting of semantic analysis is done in advance.
4Adaptability or versatility
If manual input is used for training and fine-tuning, then the model can be precisely customized, but the process requires significant manual input and time
Solution Approach 1:
The system incorporates feedback mechanisms where the vision-language models learn from user interactions and query patterns. This automated feedback loop allows the models to adapt and customize themselves without requiring continuous manual fine-tuning, maintaining high adaptability while reducing manual operational burden.
Data Source
AI summary
Systems and methods are provided for identifying and retrieving semantically similar images from a database. Semantic analysis is performed on an input query utilizing a vision language model to identify semantic concepts associated with the input query. A preliminary set of images is retrieved from the database for semantic concepts identified. Relevant concepts are extracted for images with a tokenizer by comparing images against a predefined label space to identify relevant concepts. A ranked list of relevant concepts is generated based on occurrence frequency within the set. The preliminary set of images is refined based on selecting specific relevant concepts from the ranked list by the user by combining the input query with the specific relevant concepts. Additional semantic analysis is iteratively performed to retrieve additional sets of images semantically similar to the combined input query and selection of the specific relevant concepts until a threshold condition is met.
