Chenxi Huang, C.C. Li, Nianchun Fan, Bart G. Denys, P.S. Reddy · 2005
In this paper we present an algorithm for enhancement of angiogra hic images using morphological opening filter. Opening ora gray-scale image by a gray-scale structuring element(SE) can generate a background image. To remove the background image , we can subtract it from the original image. Usually, there are a large number of computations involved in gray-scale opening operation. We present a skipped SE algorithm which can significantly improve the processing speed, and yet gives excellent enliancement for the angiographic images.
