iYUNDONG‘s AI Automatically Extracts Sporting Event Highlights

iYUNDONG builds artificial intelligence (AI) tools that analyze media captured during sporting events to automatically extract key highlights. For example, by uploading a single photo, images of individual marathon runners can be automatically retrieved from a massive dataset that includes photos and videos from the event.

iYUNDONG leverages Milvus, an open-source vector database built by Zilliz, to power its core image retrieval system.

Objective

From a single uploaded photo, accurately retrieve all images of a user from a massive, dynamic database.

Challenges

  • Return accurate search results based on user uploaded photos that vary in resolution, size, clarity, angle, and other ways that complicate similarity search.
  • Make newly uploaded photos immediately available for search.
  • Run millisecond-level queries on a database of 60+ million images.
  • Build a production ready application in one month.

Why Verctor Database

  • Thanks to Milvus’ data flushing mechanism, iYUNDONG’s backend system is faster and more efficient because resource use is distributed across different nodes.
  • Support for real-time search on trillion-vector datasets gives users instantaneous results.
  • An active open-source community and powerful out-of-the-box features allowed iYUNDONG to operate on a tight development budget.

Results

  • Accuracy rate of photo retrieval is constantly above 92%.
  • Newly uploaded photos can be searched in real time.
  • Queries completed in milliseconds on average.
  • Project finished on time and under budget.

"Milvus’ performance is unparalleled. The platform allowed us to create a powerful, enterprise-grade image retrieval system on a short timeline with limited resources."

- Xiupeng Zhou, Software Architect at iYUNDONG
