Aerial image: from straight lines to rectangles
Sergey Ablameyko, Dmitry M. Lagunovsky · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1994
A fast algorithm to detect rectangles in aerial images is suggested. A contour image is used as an input for the algorithm. the primitive lines are extracted in the contour image and joined into line segments by cluster analysis method. the line-merging algorithm is developed, and an algorithm to detect rectangles from the extracted straight lines is suggested. The developed algorithm allows a good relation between computational time and line quality.
