Exact and Approximate Solutions of the Perspective-3-point Problem

Model-based pose estimation techniques which match image and model triangles require large numbers of matching operations in real world applications. We show that by using approximations to perspective, 2D lookup tables can be built for each of the triangles of the models. An approximation called \weak perspective" has been applied previously to this problem; we consider two other perspective a...

Exact and Approximate Computational Geometry Solutions of an Unrestricted Point Set Stereo Matching Problem

In this paper we study the problem of computing an exact, or arbitrarily close to exact, solution of an unrestricted point set stereo matching problem. Within the context of classical approaches like the Marr-Poggio algorithm, this means that we study how to solve the unrestricted basic subproblems created within such approaches, possibly yielding an improved overall performance of such methods...

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

The Exact Renormalization Group and Approximate Solutions

We investigate the structure of Polchinski’s formulation of the flow equations for the continuum Wilson effective action. Reinterpretations in terms of I.R. cutoff greens functions are given. A promising non-perturbative approximation scheme is derived by carefully taking the sharp cutoff limit and expanding in ‘irrelevancy’ of operators. We illustrate with two simple models of four dimensional...
