Multiscale processing enables the network to detect objects of varying size. To achieve multiscale detection, you must specify anchor boxes of varying size, such as 64-by-64, 128-by-128, and 256-by-256. Specify sizes that closely represent the scale and aspect ratio of objects in your training data. pinecone preschool flagstaff
