Earth mover's distance emd
WebEarth Mover's Distance Description emd computes Earth Mover's Distance (related to 1st Mallows and Wasserstein distances) between distributions. emd and emdw use (weight,location) notation whereas emd2d compares two distributions represented as matrices over a grid. Usage WebDec 5, 2015 · 1 I am searching for an example Python implementation to compute the Earth Mover's Distance (EMD) between two histograms (in order to compare the similarity of two images). The answer given in this post Python code for Earth mover's Distance is exactly what I am looking for, but I need it to work with cv2.
