A gray-scale Inverse Hough Transform algorithm
Anastasios L. Kesidis, N. Papamarkos · 2002
This paper proposes a gray-scale Inverse Hough Transform. The proposed algorithm can be applied to any gray-scale image and allows the edge extraction according to filtering conditions. The algorithm exploits all the gray-scale information and avoids conversion of the gray-scale image to a binary one. The edge pixels are exactly determined according to their position and gray-level as they appear in the original gray-scale image.
