The Generic Viewpoint Constraint
نویسندگان
چکیده
| Recent work 1] has demonstrated the GBR ambiguity which is inherent in the perception of depth from shading and shadow cues. The purpose of this paper is rstly to extend the GBR transform to allow for diierent viewpoints. We demonstrate how this can be done by using image warping. This enables us to generalize the GBR to deal with situations where objects are viewed from diierent viewpoints (as well as under diierent lighting conditions). The second point is to analyze how the generic viewpoint assumption 4]interacts with the GBR. Our results show that generic viewpoint constraint disambiguates the GBR by biasing towards a at surface.

Declarative Debugging of Missing Answers in Constraint Functional-Logic Programming
It is well known that constraint logic and functional-logic programming languages have many advantages, and there is a growing trend to develop and incorporate effective tools to this class of declarative languages. In particular, debugging tools are a practical need for diagnosing the causes of erroneous computations. Recently [1], we have presented a prototype tool for the declarative diagnos...
متن کاملUsing and comparing metaheuristic algorithms for optimizing bidding strategy viewpoint of profit maximization of generators
With the formation of the competitive electricity markets in the world, optimization of bidding strategies has become one of the main discussions in studies related to market designing. Market design is challenged by multiple objectives that need to be satisfied. The solution of those multi-objective problems is searched often over the combined strategy space, and thus requires the simultaneous...
متن کاملThe Generic Viewpoint Assumption and Planar Bias
We show that generic viewpoint and lighting assumptions resolve standard visual ambiguities by biasing toward planar surfaces. Our model uses orthographic projection with a two-dimensional affine warp and Lambertian reflectance functions, including cast and attached shadows. We use uniform priors on nuisance variables such as viewpoint direction and the light source. Limitations of using unifor...
متن کاملMidcourse Trajectory Shaping for Air and Ballistic Defence Guidance Using Bezier Curves
A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...
متن کاملDual Formulations of Magic Squares
The problem of finding an n × n magic square can be represented as a constraint satisfaction problem (CSP). It can be modelled as a permutation problem, and hence there are dual viewpoints in which the roles of the variables and values are reversed. In modelling problems as CSPs, choosing between different viewpoints and the resulting models usually requires taking the constraint solver into ac...
