This paper presents a system for matching and pose estimation of 3D space curves under the similarity transformation composed of rotation, translation and uniform scaling. The system makes use of constraints not only on the feature points but also on the curve segment. A representation called the similarity-invariant coordinate system (SICS) is presented for deriving semi-local invariants of 3D...

Soil water characteristic curve shows the relationship between soil water content and matric suction, which has an important role in water movement in the soil. The measurement of this curve is expensive and time-consuming in laboratory therefore, many methods have been proposed for its estimation including pedotransfer functions. By using the pedotransfer functions, soil water characteristic c...

where the constant c = c(L, p) > 0 does not depend of n and Pn, and μn(L, h, p) → ∞, as n → ∞, depending on geometrical properties of the curve L and the weight function h in neighborhoods of {zj}mj=1. The classical results of (2)-type can be found in [5], [8]. The estimation of (2)-type was investigated by [6], [7, pp.122-133], [4], [1]-[3] and others. In this work, we investigate the conditio...
