Validate the format of the line. If the line is not valid an exception will be raised. If maxWidth and maxHeight are specified, all points mu

Args: tensor_on_gpu: (N, 1, H, W) blur: Lambda. If exists, each instance will be blured using `blur`.

Returns a Polygon object to use with the Polygon2 class from a list of 8 points: x1,y1,x2,y2,x3,y3,x4,y4

_bitmap: single map with shape (1, H, W), whose values are binarized as {0, 1}

3x3 convolution with padding

Returns a Unicode object on success, or None on failure

compute the distance from point to a line ys: coordinates in the first axis xs: coordinates in the second axis point_

Returns accuracy score evaluation result. - overall accuracy - mean accuracy - mean IU - fwavacc

_bitmap: single map with shape (1, H, W), whose values are binarized as {0, 1}

Validates that the points that the 4 points that dlimite a polygon are in clockwise order.

polygons (numpy.array, required): of shape (num_instances, num_points, 2)

Validate the format of the line. If the line is not valid an exception will be raised. If maxWidth and maxHeight are specified, all points mu
