Check out our pictures of shapes and enjoy a wide range of simple geometric shapes, 2D polygons and 3D polyhedrons. Find images of basic shapes such as circles, triangles, squares, pentagons and hexagons as well as star shapes such as pentagrams and hexagrams, quadrilaterals such as paralle...
The dilated, blurred image is subtracted pixel-wise from the original image to produce the final result Fig. 3 An illustration of a homography performing a general linear mapping of the points of one quadrilateral to another. Images suffering from perspective distortions can have much of ...
pamperspective interprets the input image as a perspective projection of another image which is in a plane oblique to that of the input image. For example, a photograph of a painting, taken at an angle. The arguments upper_left_x ... lower_right_y specify a quadrilateral in the photograph...
The extracted mesh M is a vertex set V given by (K,p), where K⊆2V is a quadrilateral simplicial complex, and V → R3 is a function, which maps every vertex i ∈ V to its position pi (Liu, Bao, Shum, Peng, 2002, Vollmer, Mencl, Mller, 1999). In a three-...
-triangle: verticies and edges are rearranged to form a triangle topography. Implementation is from:"A Remeshing Approach to Multiresolution Modeling" by M. Botsch and L. Kobbelt. CPU overhead expected. -quad: verticies and edges are rearanged in quadrilateral topography with a proper quad flow...

The AF approach involved the use what is known as a “light slab”, which basically can be described as a convex quadrilateral object composed of two main planes (u, v), and (s, t). In a two-plane parameterization, each ray in space can be represented by one point Pi = (u, v,...
In many cases, the distorted image will appear as a trapezoid or an arbitrarily shaped quadrilateral. The non-rectangular shape of the resulting projected image is referred to as keystoning. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate various embodiments of the principles ...
Step 208 determines a first dimension for the one or more of the multiple sub-images based on the guide parameter. In at least some embodiments, a sub-image can be in the shape of a square, a rectangle, a quadrilateral, or other similar shape, that has sides and dimensions for each si...
