The discrete Fréchet distance is an approximation of the Fréchet distance which measures the similarity between two curves. They are in the same x range (say -30 to 30). Various fits were attempted by varying the number of data points and outliers. Both the DTW and area metrics completely ignore outliers and find the true line. I've got some ideas in mind but I'm sure there is a better way to do it algorithmically. I was surprised to find that minimizing the DTW or area between curves produced the same results. Let’s start off by taking a look at our example dataset:Here you can see that we have three images: (left) our original image of our friends from Jurassic Park going on their first (and only) tour, (middle) the original image with contrast adjustments applied to it, and (right), the original image with the Jurassic Park logo overlaid on top of it via Photoshop manipulation.Now, it’s clear to us that the left and the middle images are more “similar” t… In practice, the KS test is extremely useful because it is efficient and effective at distinguishing a sample from another sample, or a theoretical distribution such as a normal or uniform distribution. Using perceptual hashing in Python to determine how similar two images are, with the imagehash library and Pillow. It has nice wrappers for you to use from Python. Additionally I’ve created a Python library called similaritymeasures which includes the Partial Curve Mapping method, Area between two curves, Discrete Fréchet distance, and Curve Length based similarity measures.
