Usually the reference series should have at least as many values as their are images, in which case the images to be censored are those for which the corresponding reference value is less than or equal to zero (any positive reference value means keep that image). | Usually the reference series should have at least as many values as their are images, in which case the images to be censored are those for which the corresponding reference value is less than or equal to zero (any positive reference value means keep that image). | ||
