2. Hough transform - Wikipedia

   en.wikipedia.org/wiki/Hough_transform

   The results of this transform were stored in a matrix. Cell value represents the number of curves through any point. Higher cell values are rendered brighter. The two distinctly bright spots are the Hough parameters of the two lines. From these spots' positions, angle and distance from image center of the two lines in the input image can be ...

3. Line detection - Wikipedia

   en.wikipedia.org/wiki/Line_detection

   The Hough transform [3] can be used to detect lines and the output is a parametric description of the lines in an image, for example ρ = r cos(θ) + c sin(θ). [1] If there is a line in a row and column based image space, it can be defined ρ, the distance from the origin to the line along a perpendicular to the line, and θ, the angle of the perpendicular projection from the origin to the ...

5. 2D to 3D conversion - Wikipedia

   en.wikipedia.org/wiki/2D_to_3D_conversion

   The idea of the method is based on the fact that parallel lines, such as railroad tracks and roadsides, appear to converge with distance, eventually reaching a vanishing point at the horizon. Finding this vanishing point gives the farthest point of the whole image. [15] [17] The more the lines converge, the farther away they appear to be.

7. Distortion (optics) - Wikipedia

   en.wikipedia.org/wiki/Distortion_(optics)

   In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
