  • Image segmentation
  • Object labeling
  • Geometric feature extraction

EasyObject is used for blob analysis that is obtaining information about the distinct objects that are present in an image. The processing is based on connected component labeling, to isolate and identify the objects. Then, various geometric features of the objects, such as the area or ellipse of inertia parameters, are computed and the objects are sorted and selected with respect to these features. Blob analysis is a convenient way to locate objects even without any previous knowledge of their shape, size and position, to measure these characteristics and discriminate between them.

Holes management
EasyObject allows the inspection of holes in defined objects. Holes are managed as objects themselves benefiting from the same geometrical features (area, gravity center, inertia moment, Feret box...). EasyObject library manages the relationship between objects and holes defining parent object for holes.
