Standing high jump Standing high jump The standing high jump is an athletics event that was featured in the Olympics from 1900 to 1912. It is performed in the same way as high jump, with the difference being that the athlete has no run-up and must stand still and jump with both feet together. Ray Ewry was the best of the Olympic era, setting world records for the standing high jump (1.65 m on July 16, 1900). He was also highly successful in the standing long jump and the standing triple jump. The event previously enjoyed wide competition, featuring on the Olympics athletics
Step detection is the Potts model. It is given by the non-convex optimization problem The term formula_11 penalizes the number of jumps and the term formula_12 measures fidelity to data "x". The parameter γ > 0 controls the tradeoff between regularity and data fidelity. Since the minimizer formula_13 is piecewise constant the steps are given by the non-zero locations of the gradient formula_14. For formula_15 and formula_16 there are fast algorithms which give an exact solution of the Potts problem in formula_17. Step detection In statistics and signal processing, step detection (also known as step smoothing, step filtering, shift detection, jump detection
