1. 1. A Variational Approach to Image Diffusion in Non-Linear Domains

   Författare :Freddie Åström; Michael Felsberg; Tony Lindeberg; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Image filtering methods are designed to enhance noisy images captured in situations that are problematic for the camera sensor. Such noisy images originate from unfavourable illumination conditions, camera motion, or the desire to use only a low dose of ionising radiation in medical imaging. LÄS MER
