Bilateral Filtering: VCD and form system ä Think: form system input to diffusion process, and diffusion. ä Blurs within boundary by using a weighting function that is the product of two Gaussians: ä Gaussian with a spatial kernel: closer pixels have higher weight. ä Gaussian in the intensity domain: higher weights for pixels with similar intensities. ä Dorsey, 2002 ä Think: form system input to diffusion process, and diffusion. ä Blurs within boundary by using a weighting function that is the product of two Gaussians: ä Gaussian with a spatial kernel: closer pixels have higher weight. ä Gaussian in the intensity domain: higher weights for pixels with similar intensities. ä Dorsey, 2002
