“…For the precise extraction of the region of interest (ROI), wheat canopy segmentation experiments were conducted to evaluate seven segmentation strategies, viz., global static thresholding, global automatic thresholding (Otsu), mean shift, edge detection operators, k-means (based on four means), watershed, and the “Cfit K-means algorithm” ( Gupta, Kaur & Kaur, 2022b ). The IOU (intersection over union) metric score has been used for the validation of the segmentation of regions of interest (wheat canopy).…”
