Abstract
This paper presents a new version of the exact discrete Radon [1] transform denoted as Mojette transform. Whereas the Mojette transform backprojects a single bin into a grey value pixel at each iteration, the proposed version backprojects a bin onto an entire segment of binary pixels. Implementation of this discrete exact backprojector is presented and used for specific binary images of incomplete contours giving a new representation of 2D edges images.
