# distance_two_indices¶

menpofit.error.distance_two_indices(index1, index2, shape)[source]

Computes the Euclidean distance between two points of a shape, i.e.

$\sqrt{(s_{i,x}-s_{j,x})^2 + (s_{i,y}-s_{j,y})^2}$

where $$s_{i,x}$$, $$s_{i,y}$$ are the x and y coordinates of the $$i$$’th point (index1) and $$s_{j,x}$$, $$s_{j,y}$$ are the x and y coordinates of the $$j$$’th point (index2).

Parameters
• index1 (int) – The index of the first point.

• index2 (int) – The index of the second point.

• shape (menpo.shape.PointCloud) – The input shape.

Returns

distance_two_indices (float) – The Euclidean distance between the points.
