i have this array of y-coordinates of elbowleft joint. can visualize here. now, want come solution can count number of peaks or local maximum in array.

you try smooth data smoothing filter , find values value before , after less current value. assumes want peaks in sequence. reason need smoothing filter avoid local maxima. level of smoothing required depend on noise present in data.

a simple smoothing filter sets current value average of n values before , n values after current value in sequence along current value being analyzed.
