متن کاملIndoor Polar Panoramas Using a Rectified Lambert Azimuthal Equal-Area Projection
We present an algorithm for converting an indoor spherical panorama into a photograph with a simulated overhead view. The resulting image will have an extremely wide field of view covering 4π steradians of the spherical panorama. Our method provides the photographer the ability to shoot at the ground level and later post-process the pictures to get a fake bird’s eye view of the scene. We argue ...
متن کاملUniform spherical grids via equal area projection from the cube to the sphere
We construct an area preserving map from the cube to the unit sphere S, both centered at the origin. More precisely, each face Fi of the cube is first projected to a curved square Si of the same area, and then each Si is projected onto the sphere by inverse Lambert azimuthal equal area projection, with respect to the points situated at the intersection of the coordinate axes with S. This map is...
متن کاملLipschitz Extension Constants Equal Projection Constants
For a Banach space V we define its Lipschitz extension constant, LE(V ), to be the infimum of the constants c such that for every metric space (Z, ρ), every X ⊂ Z, and every f : X → V , there is an extension, g, of f to Z such that L(g) ≤ cL(f), where L denotes the Lipschitz constant. The basic theorem is that when V is finite-dimensional we have LE(V ) = PC(V ) where PC(V ) is the well-known p...
متن کاملEqual Area World Maps: A Case Study
If one wishes to produce a world map that displays area-based data, such as the extent of rain forests, the range of butterfly migrations, or the access of people in various regions to medical facilities, then it is often appropriate to use a base map that shows the areas of all regions of the earth’s surface in their correct proportions. Such a map is called an equal area or equivalent map by ...
