Download e-book for iPad: Mathematical Morphology and its Applications to Image and by Petros Maragos, Visit Amazon's Ronald W. Schafer Page,

Mathematical morphology (MM) is a strong method for the quantitative research of geometrical buildings. It comprises a vast and coherent choice of theoretical suggestions, nonlinear sign operators, and algorithms aiming at extracting, from pictures or different geometrical gadgets, info relating to their form and dimension.

It has, however, one demerit that the direct acoustical coupling between the transmitter and the receiver must be excluded by an acoustical absorber placed between them, although the electrical coupling is easily kept away with the electrical shield. This may limit somewhat practical utility of this method. , poor axial resolution in the first type and necessity of placing an acoustical absorber in the second type. First, we made imaging placing the transmitter and receiver arrays, both of which are composed of 37 elements, on a line as in the first type, but using five different frequencies.
