Figure 14-23. Intersection over Union (IoU) Metric for Bounding Boxes Classifying and localizing a single object is nice, but what if the images contain multi‐ple objects (as is often the case in the flowers dataset)? Object Detection The task of classifying and localizing multiple objects in an image is calledobject detection.

WebAn edge device for image processing includes a series of linked components which can be independently optimized. A specialized change detector which optimizes the events collected at the expense of false positives is accompanied by a trainable module, which uses training feedback to reduce the false positives over time.
