## Summary

Kat Scott, a senior software engineer at Planet and co-author of 'Practical Computer Vision with SimpleCV', explains the fundamentals of computer vision, emphasizing that it is largely about discarding irrelevant data to find specific signals. She details the challenges of industrial computer vision, noting that consistent lighting and constrained environments are critical for success, and warns that achieving high accuracy in machine learning requires exponentially more data for each decimal place of improvement. Scott also discusses the technical pipeline behind real-time face filters like those on Snapchat, which involve face detection, 3D mesh fitting, and reprojection, and advises engineers to use tools like OpenCV and ROS rather than reinventing the wheel.
