Comments on “Weed recognition using image blur information” by Peng, Z. & Jun, C., Biosystems Engineering 110 (2), p. 198–205

• This paper is a reaction to the recent paper published in this journal.
• We show how moment invariants could be used in a weed recognition system.
• We explain how the recognition rate could be increased.

This research note is in reaction to a recent paper on weed recognition using image analysis (Peng & Jun, 2011). Here, the correct use of moment invariants in a weed recognition system is presented.
