MOMENT INVARIANTS OF OPEN CURVE FOR FUSION
Zhou-bao Liao, Zhao Liu · 2006
This paper presents a new set of moment invariants used for the fusion of open curve target. The moment invariants of open curve are reformulated on that of close curve. The indexes and rules for fusion of open curve target are founded on those invariants. Several retrieving methods of open curve in sparse sampling are compared to obtain appropriate ones. Determination of fusion threshold is discussed. Experiments show that these invariants were effective infusion of open curve target
