root_mean_square_error
(shape, gt_shape)[source]¶ Computes the root mean square error between two shapes, i.e.
\[\sqrt{\frac{1}{N}\sum_{i=1}^N(s_i-s^*_i)^2}\]where \(s_i\) and \(s^*_i\) are the coordinates of the \(i\)’th point of the final and ground truth shapes, and \(N\) is the total number of points.
- Parameters
shape (menpo.shape.PointCloud) – The input shape (e.g. the final shape of a fitting procedure).
gt_shape (menpo.shape.PointCloud) – The ground truth shape.
- Returns
root_mean_square_error (float) – The root mean square error.
