propriedades. O momento bidimensional padrão é uma função projetada em f(x,y), representando uma imagem através de uma função polinomial. Pode-se definir o momento bidimensional de ordem (p+q) de uma imagem digital f(x,y) de tamanho M × N como: m pq = M − 1N − 1 ∑ ∑ x p yq f ( x,y ) x=0 y=0 Eq. (6) onde p, q ∈ z Os momentos bidimensionais podem não ser invariantes a transformações como translação Φ 5 = (η30 − 3η12 )(η30 + η12 ) [(η30 + η12 ) 2 −3 (η21 + η03 ) ] + 2 ou…

latter added to keep the SnO2 in solution and thus retain a surface exposed to the action of the acid. For etching aluminum a 9% solution of CuCl3 in 1% acetic acid, or a 20% solution of FeCl3 may be used, followed by a wash with strong HNO3 acid. NaOH, NH4OH, or any alkaline solutions are also used for etching aluminum. Zinc is preferably etched with weak HNO 3 acid, but requires a frequent renewal of the acid. Strong acid is not used because of the heat generated, which destroys the…
