3-D polyhedral object recognition using fuzzy indicators

Fuzzy logic has been used during the past years for determination and analysis of visual properties and spatial relations in object regions, a fundamental key for the object recognition problem. Here we present a method which quantifies the number of sides of each region of an object of a light intensity image, a measurement that can be used as a helpful aid to identify objects. We add this new property, the fuzzy number of sides, to other fuzzy measurements commonly used in object identification, such as area, diameter, roundness, and elongatedness, and we obtain a useful improvement in reliability for object recognition
