abstract = "The analysis of images depends on the scale of the objects of interest. The extent of each real world object is limited by two scales: the inner and outer scale [1]. The inner scale corresponds to the resolution which expresses the pixel size and is determined by the resolution of the sampling device. The outer scale of an object corresponds to the minimum size of a window that completely contains the object, and is consequently limited by the field of view. In controlled environment, these two scales are known",
