The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...
Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.
Modification of the free and open-source graphics program GNU Image Manipulation Program (GIMP), with the intent to be a free alternative to Adobe Photoshop.

Most graphics editing programs, such as Adobe Photoshop and GIMP, allow users to modify the basic blend modes, for example by applying different levels of opacity to the top "layer". The top "layer" is not necessarily a layer in the application; it may be applied with a painting or editing tool.

Includes 2D homography from four pairs of corresponding points, mosaics in image processing, removing perspective ...
Elastic Reality made its name with the ease of use of its tool, and the quality of the resulting warps. Other warping tools have typically offered a simpler warping and morphing based on animating points on a grid, which can require significantly more work from the artist to animate distortion of organic shapes such as human faces.
Photo manipulation dates back to some of the earliest photographs captured on glass and tin plates during the 19th century. The practice began not long after the creation of the first photograph (1825) by Joseph Nicéphore Niépce who developed heliography and made the first photographic print from a photoengraved printing plate.
Mapping a two-dimensional texture onto a 3D model 1: 3D model without textures 2: Same model with textures. Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models.
