Beyond the theoretically challenging question as to whether participles should be considered inflectional or derivational forms, homography causes problems too.
The topics include a close-range photogrammetric solution working with zoomed images from digital cameras, a four-point planar homography algorithm for rectification photogrammetry: development and applications, applying camera matching methods to laser-scanned three-dimensional scene data with comparisons to other methods, evaluating the accuracy of image-based scanning as a basis for the photogrammetric reconstruction of physical evidence, and evaluation two methodologies for lens distortion removal when exchangeable image file format data is unavailable.

Thus, we can estimate the checkerboard corner locations in the projector pixel coordinates based on a local homography [6] as an illustration in Figure 3.
Then, positions of corner points in corrected images and their target positions are used to compute homography matrix H.
The image registration stage has the following three steps: find the features, match these features, and then find the homography matrix.
Further, as the lens is supposed to be planar and symmetric about optical axis, two-angle parameters should be sufficient to express the homography between the tilted image plane and ideal image plane [23, 27].
The feature-based tracking algorithm utilizes a homography file that projects the camera image space to the real-world ground plane.
[7] proposed a novel image warping algorithm which applied a global homography H as a simple model to describe the relationship of the two adjacent views.
Secondly, since the proposed method rotates the trimmed input image, it is necessary to calculate a homography matrix describing the relationship between corresponding points as shown in equation (3).
