Long jump at the Olympics gold medals in its brief history. From 1900 to 1912 a variation of the event was contested at the Olympics where athletes had to long jump from a standing position. This was one of three standing jumps to have featured on the Olympic programme, alongside the standing high jump (present for the same period) and the standing triple jump (1900 and 1904 only). The standing jump competitions were dominated by Ray Ewry, who won the Olympic standing long jump titles in 1900, 1904 and 1908. His clearance of at the 1904 Olympics remained as the Olympic record for the event
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
