enter image description hereI have a time series signal and using this as reference, from the main data set extracted possible matching sections using cross correlation technique.(xcorr matlab).Based on with the threshold xcorr value used to extract it may contain some not-matching signals as well( slight difference).

I am looking for a way to further analyse the output and remove the not-matching signals. Any better way to do that ? Since I used cross correlation method(mathematical) would it be beneficial to use image analysis of the two signals ?

Reference picture attached.
