Linking Canny Edge Pixels with Pseudo-watershed Lines
Published
Author(s)
Abstract
A method is presented for computing pseudo-watershed lines that can be used for linking pixels that have been identified as edge pixels with the Canny edge detector. An additional procedure is also described for filling breaks that may still exist between these lines and that takes advantage of the data structure for computing pseudo-watershed lines. We have implemented the Canny edge detector together with these methods, and have demonstrated the ability of the implementation to produce complete characterizations of outer boundaries of cells in an image.Citation
