This op generate anchors for Faster RCNN algorithm.
Each position of the input produce N anchors, N =
size(anchor_sizes) * size(aspect_ratios). The order of generated anchors
is firstly aspect_ratios loop then anchor_sizes loop.
Args:
input(Tensor): 4-D Tensor with shape [N,C,H,W]. The input feature map.
anchor_sizes(float32|list|tuple, optional): The anchor sizes of generated
anchors, given in absolute pixels e.g. [64., 128., 256., 512.].
For instance, the anchor size of 64 means the area of this anchor
equals to 64**2. None by default.
aspect_ratios(float32|list|tuple, optional): The height / width ratios
of generated anchors, e.g. [0.5, 1.0, 2.0]. None by default.
variance(list|tuple, optional): The variances to be used in box
regression deltas. The data type is float32, [0.1, 0.1, 0.2, 0.2] by
default.
stride(list|tuple, optional): The anchors stride across width and height.
The data type is float32. e.g. [16.0, 16.0]. None by default.
offset(float32, optional): Prior boxes center offset. 0.5 by default.
name(str, optional): For detailed information, please refer
to :ref:`api_guide_Name`. Usually name is no need to set and None
by default.
Returns:
Tuple:
Anchors(Tensor): The output anchors with a layout of [H, W, num_anchors, 4].
H is the height of input, W is the width of input,
num_anchors is the box count of each position.
Each anchor is in (xmin, ymin, xmax, ymax) format an unnormalized.
Variances(Tensor): The expanded variances of anchors
with a layout of [H, W, num_priors, 4].
H is the height of input, W is the width of input
num_anchors is the box count of each position.
Each variance is in (xcenter, ycenter, w, h) format.
