1. A method for estimating on a curve a relevant point for detecting an anomaly of an engine, said curve representing a time-dependent change in physical operation parameters of the engine measured by at least one sensor on said engine,applied by a computer connected to first storage means,said first storage means storing in memory at least one profile comprising a binary code, each component of which codes a direction of variation between two consecutive characteristic points of at least one learning curve, a model allowing estimation of a relevant point from a set of characteristic points of a curve, and a filter,said method comprising:

  • a/ selecting a profile stored in memory in the first storage means;

    b/ applying the filter of the selected profile to said curve;

    c/ determining a set of characteristic points of said filtered curve and of a binary code, each component of which codes the direction of variation of two consecutive characteristic points belonging to said set of characteristic points;

    d/ comparing the determined code and the code of the selected profile;

    e/ depending on said comparison, estimating the relevant point on said curve from the characteristic points of said filtered curve and from the model of the selected profile.
