Analysis and Design of Dirty Paper Coding by Transformation of Noise
— We design a coding scheme for Costa’s dirty paper coding (DPC) [6] using a channel and a shaping code. We show that by transforming the channel noise distribution the DPC cha...

Using an Extended Hough Transform Combined with a Kalman Filter to Segment Tubular Structures in 3D Medical Images
We present a new approach for the coarse segmentation of tubular structures in 3D image data. Our algorithm, which requires only few initial values and minimal user interaction, c...

Image Contrast Enhancement Based on a Histogram Transformation of Local Standard Deviation
Abstract— The adaptive contrast enhancement (ACE) algorithm, which uses contrast gains (CG’s) to adjust the highfrequency components of images, is a well-known technique for me...
