Abstract

Nowadays, a goodness digital compactness measure is necessary in computer vision, shape analysis and computer medical diagnosis process where digital picture are used widely. We introduce a compactness measure called Normalized E-Factor which shows as a measure robust to translations, rotations and scale-changes and that it satisfies the set of criteria for a good compactness measure. Through a series of experiments, we show that the Normalized E-Factor is useful for shape description, measuring digital compactness with or without holes and that it overcomes some drawbacks that present several compactness measures over digital space..
