Weiqian Lin · Applied and Computational Engineering · 2023
In original images/videos, disturbance and noise are inevitable. Therefore, image and video filtering technology has been proposed and developed rapidly. In recent years, bilateral filtering has been widely utilized as an efficient filtering method that can effectively preserve edge information while reducing noise. Researchers have extensively studied the bilateral filtering algorithm and its hardware structures, generating several excellent optimization methods. This paper will comprehensively analyze typical bilateral filtering algorithms and hardware structure optimization design. Some directions for future bilateral filtering optimization will be provided, including algorithms and hardware structures, with analysis and discussion.
