Triple jump at the Olympics to 1912). The standing jump competitions were dominated by Ray Ewry, who won the 1900 Olympic standing triple jump title and defended it four years later. His clearance of to win the inaugural competition went unbettered as the Olympic record for the event. Ewry took Olympic three gold medals in standing jumps in both 1900 and 1904, then won the standing high and long jumps at the 1908 Olympics, as well as the 1906 Intercalated Games. Standing jump events had been a relatively common type of athletics event at the end of the 19th century, but became increasingly rare at
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
