Image Analysis to Estimate Mulch Residue in Soil

Table 2

Computational time (in minutes) for the calculation of soil area in binary images obtained by several thresholding methods: Otsu (OT), Ridler-Calvard (RC), local entropy (LE), manual thresholding (MT), and reference area (). This time has been estimated based on a set of 24 color images. The ratio has been calculated with respect to MT method.
