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...
Example of an exact mask (a) of solar cells estimated using the proposed approach and a quadrilateral mask (b) determined from the exact mask. The latter is used for comparison against the method of Sovetkin and Steland [86]. Both masks are shown as color overlays. Different colors denote...
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 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 ...
-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 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-...

(FIG.4A). InFIG. 4B, there is shown the construction of a typical bilinear element on a quadrilateral Q=[Z1Z2Z3Z4] with known node valuesƒn(zi), i=1:4. Essentially, this construction is a Gouraud interpolation with the scan line rotated to be parallel with the least discrepancy...
if this alignment or orientation is not made, the resulting image on the display surface may be distorted. 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...
