There is a growing interest in OpenCV and TensorFlow Lite, mainly due to the hype around LLMs. This talk will guide attendees on how to use these tools on Android and explain the tasks they are best suited for. The presentation is based on real-world experiences of supporting the Caper Cart computer vision (CV) team at Instacart. We will begin by discussing the fundamental concepts of OpenCV and TensorFlow Lite, followed by their implementation in practical computer vision scenarios. The presentation will offer valuable insights on image and video analysis, object detection, and real-time object tracking, all of which are essential components in the development of the Caper Cart product. During the discussion, we will talk about the challenges faced during development and the solutions found. We'll also focus on using tools like Perfetto to optimize performance in CV applications.
