tfm.vision.anchor_generator.AnchorGenerator

Utility to generate anchors for a multiple feature maps.

tfm.vision.anchor_generator.AnchorGenerator(
    anchor_sizes, scales, aspect_ratios, strides, clip_boxes=False
)

anchor_gen = AnchorGenerator([32, 64], [.5, 1., 2.],
  strides=[16, 32])
anchors = anchor_gen([512, 512, 3])

Args
`anchor_sizes`	A list of int represents the anchor size for each scale. The anchor height will be `anchor_size / sqrt(aspect_ratio)`, anchor width will be `anchor_size * sqrt(aspect_ratio)` for each scale.
`scales`	A list/tuple, or a list/tuple of a list/tuple of positive floats representing the actual anchor size to the base `anchor_size`.
`aspect_ratios`	A list/tuple, or a list/tuple of a list/tuple of positive floats representing the ratio of anchor width to anchor height.
`strides`	A list/tuple of ints represent the anchor stride size between center of anchors at each scale.
`clip_boxes`	Boolean to represents whether the anchor coordinates should be clipped to the image size. Defaults to `False`.
