-Bird bar is a bird feeder with a camera on it. Each frame from the camera's video feed is run through a classifier model to recognize any birds in the picture. Each bird is labeled with its species above its head and the resulting video is live-streamed to the internet. Species data is collected in a time series database.+Bird bar is a bird feeder with a camera on it. A computer vision model watches the feed to identify the species of birds that visit the feeder.

With a TensorRT-optimized kernel and recent firmware upgrades to the board to unlock additional performance, classification takes about 50 ms/frame, achieving around 20 frames per second. Classification runs at 480x800 resolution.
