<title>Feature matching and improved Hough transform in visible measurement</title>

Abstract

This paper presents a new idea of Epipolar Slope. There are some feature points, e.g. the inflection point, on the epipolar line or curve. The homonymous points can be discovered in a couple images, and Feature Matching can be achived as visible measurement,. The Improved Hough Transform has been discussed in this paper because the standard quadratic curve may be discovered by the Improved Hough Transform as the pre-process of the Feature Matching.
