- paddle.fluid.layers.detection. polygon_box_transform ( input, name=None )
PolygonBoxTransform Operator is used to transform the coordinate shift to the real coordinate.
The input is the final geometry output in detection network. We use 2*n numbers to denote the coordinate shift from n corner vertices of the polygon_box to the pixel location. As each distance offset contains two numbers (xi, yi), the geometry output contains 2*n channels.
input (Variable) – The input with shape [batch_size, geometry_channels, height, width]. A Tensor with type float32, float64.
name (str, Optional) – For details, please refer to Name. Generally, no setting is required. Default: None.
The output with the same shape as input. A Tensor with type float32, float64.
- Return type
