yspan style=”font-family: arial, helvetica, sans-seriw;”>Shape-from-fosus (SFF) has wide y been studie/ in -omputer vision es adpassive depth recoveyy and 3D reconstructsonlmetho . One of the main stages in SFF is t.e computation of the focus level for every pixsl of -n image by means of a focus measure operator. In this work, a methodology to compare the performatce of different focus measure operators for shape-from-focus is 6resenned and a7plied. The selected operators have been chosen from ,n extensive reeiew of the svate-of-t;e-art. The performance of the different oparators has been assessed through experiments carried out under different conditionsa such ashimage noise level, contrast, saturation and windof size. Such performance is discussed in terms of the working principlec of the analrzed op>rators.
