Separating Rigid Motion for continuous Shape Evolution
A method is proposed for the construction of descent directions for the minimization of energy functionals defined for plane curves. The method is potentially useful in a number of image analysis problems, such as image registration and shape warping, where the standard gradient descent curve evolutions are not always feasible. The descent direction is constructed by taking a weighted average o...
متن کاملAn Experimental Comparison of Discrete and Continuous Shape Optimization Methods
Shape optimization is a problem which arises in numerous computer vision problems such as image segmentation and multiview reconstruction. In this paper, we focus on a certain class of binary labeling problems which can be globally optimized both in a spatially discrete setting and in a spatially continuous setting. The main contribution of this paper is to present a quantitative comparison of ...
متن کاملContinuous Rigid Functions
A function f : R→ R is vertically [horizontally] rigid for C ⊆ (0,∞) if graph(cf) [graph(f(c ·))] is isometric with graph(f) for every c ∈ C. f is vertically [horizontally] rigid if this applies to C = (0,∞). Balka and Elekes have shown that a continuous function f vertically rigid for an uncountable set C must be of one of the forms f(x) = px+q or f(x) = pe + r, this way confirming Jancović’s ...
متن کاملShape matching under rigid motion
We present improved algorithms to match two polygonal shapes P and Q to approximate their maximum overlap. Let n be their total number of vertices. Our first algorithm finds a translation that approximately maximizes the overlap area of P and Q under translation in Õ(n2ε−3) time. The error is additive and it is at most ε · min{area(P ), area(Q)} with probability 1 − n−O(1). We also obtain an al...
متن کاملContinuous time portfolio optimization
This paper presents dynamic portfolio model based on the Merton's optimal investment-consumption model, which combines dynamic synthetic put option using risk-free and risky assets. This paper is extended version of methodological paper published by Yuan Yao (2012). Because of the long history of the development of foreign financial market, with a variety of financial derivatives, the study on ...
