Hold an object up to the camera and Spotter labels it with a terminal-style bounding box and a confidence score.
It runs EfficientDet-Lite0 through MediaPipe's ObjectDetector. An object detector looks at each frame, proposes boxes and gives each one a category from a fixed list of everyday things. The code keeps up to six detections a frame, and only shows those scoring 0.5 or higher. It runs in your browser with the GPU delegate.
It only knows its fixed label set, so unusual objects get skipped or mislabelled.
