Standing triple jump long stretched step, landing on the opposite foot. The last phase is the jump, where the athlete lands on both feet. The winner is the competitor who achieves the longest distance on one of the 3 or 6 attempts. Competitions in standing triple jump are not very common today, but the event was included in the 1900 and 1904 Summer Olympics. Standing triple jump Standing triple jump is an athletics event based on the conventional triple jump with three jumping phases, but without an approach run-up. It is one of three standing variants of track and field jumping events, along
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
