Function opencv::shape::emdl1

pub fn emdl1(
    signature1: &dyn ToInputArray, 
    signature2: &dyn ToInputArray
) -> Result<f32>

Computes the "minimal work" distance between two weighted point configurations base on the papers "EMD-L1: An efficient and Robust Algorithm for comparing histogram-based descriptors", by Haibin Ling and Kazunori Okuda; and "The Earth Mover's Distance is the Mallows Distance: Some Insights from Statistics", by Elizaveta Levina and Peter Bickel.

Parameters

• signature1: First signature, a single column floating-point matrix. Each row is the value of the histogram in each bin.
• signature2: Second signature of the same format and size as signature1.
