Image Processing Algorithms Interview Question:

Explain What is Rectification in image processing?

Submitted by: Administrator

Image rectification is a transformation process used to project two-or-more images onto a common image plane. It corrects image distortion by transforming the image into a standard coordinate system.

It is used in computer stereo vision to simplify the problem of finding matching points between images.
It is used in geographic information systems to merge images taken from multiple perspectives into a common map coordinate system.
