Myer Prinstein restrained from doing so. The following day, he won the gold medal in the hop, step and jump (triple jump), beating 1896 champion James Connolly with a leap of 14.47 meters which simultaneously set the Olympic Record. Competing as a member of the Irish American Athletic Club in St. Louis 1904 he won both the long jump (setting a new Olympic record) and the hop, step and jump on the same day, the only athlete ever to win both events in the same games. He also came 5th in both the 60 m and 400 m dash. In Athens 1906
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
