Abstract
This paper presents a multilevel algorithm for
straight line extraction and matching from stereo in­
tensity images based on fuzzy strategies. The ultimate
goal of our work is to find 3D landmarks represented
in the form of straight lines. In this method line ex­
tracting not only uses the information of current level
but also considers the lines extracted at the coarser
level. The idea is similar to multi­scale edge focusing,
except that a fuzzy evaluation procedure is carried out
to control the quality of a line candidate. This paper
also proposes a new matching strategy based on fuzzy­
sets, where various matching constraints can be effec­
