Shotgun Pellet Analyzer

Take a clean high-resolution picture of a shotgun pattern. This app will count the pellets inside the circle or find the circle automatically. Use the bounding box feature to constrain the search and ignore background clutter if needed. Results can be manually adjusted by panning/zooming and inspection - add pellets by clicking, remove them by long-pressing on them. Both white paper and cardboard tend to work best. Do not use on a pattern plate (yet). Visit the support link for more details on the app and how to generate proper patterns.
