EasyObject is used for blob analysis. It gathers informations about distinct objects 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. 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.

• area (amount of pixels)
• width and height of bounding box
• Ferret diameter at:
  0, 22, 45, 68, 90, 112, 135 and 158 degree
• Inertial eclipse parameters
• moment of inertia
• Centroid (optical weighted centre)
• minimum, maximum, mean and variance of the grey values
• perimeter
• and much more .......
