Query by Content

Query by Content (QBC) is a method used in digital databases and search engines to find items, like images or videos, based on their actual content rather than just tags or descriptions. Instead of searching for keywords, it analyzes the visual or audio features—such as colors, shapes, or patterns—within the content. This allows users to input a sample or describe what they're looking for, and the system retrieves similar items based on those features. QBC improves search accuracy for multimedia content, making it easier to find relevant media through actual content analysis.
