Reprojection involves the headset's driver taking one or multiple previously rendered frames and using newer motion information from the headset's sensors to extrapolate (often referred to as "reprojecting" or "warping") the previous frame into a prediction of what a normally rendered frame would look like. [2] "Asynchronous" refers to this ...
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 ...
Graphical time warping (GTW) is a framework for jointly aligning multiple pairs of time series or sequences. [1] GTW considers both the alignment accuracy of each sequence pair and the similarity among pairs.
Warpalizer is a professional warp and blend software application made by Univisual Technologies AB in Sweden, for use in simulators. [1] [2] [3] [4]Warpalizer can be used for projection on to surfaces that need image geometry correction (warping) to improve the image from the projector, on a cylindrical screen for example.
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.

Automatic vehicle location (AVL or ~locating; telelocating in EU) is a means for automatically determining and transmitting the geographic location of a vehicle. This vehicle location data , from one or more vehicles, may then be collected by a vehicle tracking system to manage an overview of vehicle travel.
DivX offers 1 warp-point GMC encoding: This enables easier hardware support in DivX certified and non-certified devices. But as 1 warp-point GMC limits the global transform to panning operation only (since panning can be described using blocks), this implementation rarely improves video quality.
