WebApr 21, 2009 · Summary. Collecting weed exact counts in an agricultural field is easy but extremely time consuming. Image analysis algorithms for object extraction applied to pictures of agricultural fields may be used to estimate the weed content with a high resolution (about 1 m 2), and pictures that are acquired at a large number of sites can be … WebAbstract. The Model-free Prediction Principle of Politis (Test 22 (2):183–250, 2013) has been successfully applied to both regression problems, as well as problems involving stationary time series.
