MEASUREMENTS ON FUNCTIONS - PARAMETRICAL CHARACTERIZATION OF GRAY TONE LEVELS IMAGES AND APPLICATION TO NONPLANAR SURFACES

The purpose of image analysis is to quantify them using parameters. To obtain this result, it is necessary to eliminate noise, to extract th e objects using segmentation and finally to measure them. Unfortunatel y, all images are not segmentable, expecially topographic images obtai ned by confocal microscopy or scanning electronic microscopy. In this article, a critical study is presented for methods making it possible to obtain a quantification of information on images non segmented into levels of grey.
