With similar goal as the Bilateral filter, the class of edge-preserving smoothing filters also includes : Anisotropic Diffusion, the Weighted Least Squares framework, the Edge-Avoiding Wavelets, Geodesic editing, Guided filtering, and the Domain Transform framework.

Weickert did his undergraduate studies at the University of Kaiserslautern and then stayed there as a graduate student, earning his doctorate in mathematics in 1996 under the supervision of Helmut Neunzert; his dissertation was titled " Anisotropic Diffusion in Image Processing ".

In the fields of image processing, computer vision, and computer graphics, Heeger worked on motion estimation and image registration, wavelet image representations, anisotropic diffusion ( edge-preserving noise reduction ), image fidelity metrics ( for evaluating image data compression algorithms ), and texture analysis / synthesis.

In image processing and computer vision, "'anisotropic diffusion "', also called "'Perona Malik diffusion "', is a technique aiming at reducing image noise without removing significant parts of the image content, typically edges, lines or other details that are important for the interpretation of the image.
