Earth mover's distance emd
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. WebThe EMD is defined as the minimum amount of work needed to change one signature into the other. The notion of "work" is based on the user-defined ground distance which is …

Webearth_movers_distance (dist1, dist2, distances=None) [source] ¶ Compute the Earth Mover’s Distance (EMD) between dist1 and dist2. The EMD is the least amount of “probability mass flow” that must occur to transform dist1 to dist2. Parameters. dist1 (Distribution) – The first distribution. dist2 (Distribution) – The second distribution. WebCompute the first Wasserstein distance between two 1D distributions. This distance is also known as the earth mover’s distance, since it can be seen as the minimum amount of “work” required to transform u into v, where “work” is measured as the amount of distribution weight that must be moved, multiplied by the distance it has to be moved.
Websignature and of the Earth Mover’s Distance (EMD), which we apply to color and texture in Section 5. We compare the results of image retrieval using the EMD with those obtained with other metrics, and demon-strate the unique properties of the EMD for texture-based retrieval. Section 6 concludes with a summary and plans for future work. 2 ... WebThe Earth Mover’s Distance (EMD) is a popular distance metric for data represented as probability distributions over a predefined feature space. Generally, the solutions to the EMD are obtainable using methods from linear programming (e.g., transportation simplex), with empir-ically observed complexity of O(n3), with nbeing the
