input tensor is NCHW. Where N is batch size, C is the
number of input channels, H is the height of the feature,
and W is the width of the feature.
rois (Variable): ROIs (Regions of Interest) to be transformed. It should be
a 2-D LoDTensor of shape (num_rois, 8). Given as
[[x1, y1, x2, y2, x3, y3, x4, y4], ...], (x1, y1) is the
top left coordinates, and (x2, y2) is the top right
coordinates, and (x3, y3) is the bottom right coordinates,
and (x4, y4) is the bottom left coordinates.
transformed_height (integer): The height of transformed output.
transformed_height (integer): The width of transformed output.
spatial_scale (float): Spatial scale factor to scale ROI coords. Default: 1.0
Returns:
Variable: The output of ROIPerspectiveTransformOp which is a 4-D tensor with shape
(num_rois, channels, transformed_h, transformed_w).
