Triple jump at the Olympics successful nation in the event, with eight gold medals to its name. The Soviet Union is the next most successful, with four golds. A short-lived standing triple jump variant of the event was contested in 1900 and 1904 and standing jumps specialist Ray Ewry won both gold medals. In 1900 and 1904 a variation of the event was contested at the Olympics where athletes had to triple jump from a standing position. This was one of three standing jumps to have featured on the Olympic programme, alongside the standing high jump and the standing long jump (both running from 1900
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
