“…Analytical approaches include constructing a background model using the median pixel value (Miguel, Beery, Flores, Klemesrud, & Bayrakcismith, 2016), a non-parametric approach where the pixellevel background model is represented by a set of background samples (Barnich & Van Droogenbroeck, 2011) and robust principle component analysis (RPCA) (Candès, Li, Ma, & Wright, 2011). Unfortunately, the success of these efforts has been limited by producing large number of false positives and difficulty in distinguish between animal and human objects.…”
