Triple jump the mid-1980s. The IAAF changed the rules following outrage at the 1980 Summer Olympics in Moscow, when Russian field officials in the Men's Triple Jump ruled as foul 8 of the 12 jumps made by two leading competitors (from Brazil and Australia) thus helping two Russian jumpers win the Gold and Silver medals. "Note: Results cannot count towards records if they are Wind assisted (>2.0 m/s)." Triple jump The triple jump, sometimes referred to as the hop, step and jump or the hop, skip and jump, is a track and field event, similar to the long jump. As a group,
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
