“What If Your Camera Could Talk? Edge AI with Cascaded CV and VLMs”
In this episode and the accompnying YouTube video (https://www.youtube.com/watch?v=ZggetZn2XQY), you will gain insight into model cascading, a powerful edge AI pattern where multiple AI models are chained together on a single edge deviceYou will learn how this approach leverages a lightweight model for rapid, common inferences, conditionally triggering a heavier, more complex model for deeper understanding when needed, effectively acting as a "triage system". This showcases the ability to achieve semantic understanding of the physical world in real-time without sending data to the cloud. You will understand the significant advantages of running both models on the same edge device, which include real-time operation, low latency, privacy preservation, reduced bandwidth and cost, and enhanced power and compute efficiency, ultimately resulting in a scalable, maintainable, and future-proof edge AI pipelineFurthermore, the episode will highlight the broad applicability and generalizability of this architecture across various real-world scenarios, such as retail for shopper analysis, smart cities for vehicle behavior insights, industrial safety for human posture and behavior analysis, and agriculture for plant health assessment. This combination of fast computer vision with semantic VLM inference unlocks capabilities far beyond what either model could achieve alone6, encouraging developers to explore similar on-device cascading models for applications like gesture detection with intent understanding or defect detection with root cause explanation
