- Bilateral_filter abstract "A bilateral filter is a non-linear, edge-preserving and noise-reducing smoothing filter for images. The intensity value at each pixel in an image is replaced by a weighted average of intensity values from nearby pixels. This weight can be based on a Gaussian distribution. Crucially, the weights depend not only on Euclidean distance of pixels, but also on the radiometric differences (e.g. range differences, such as color intensity, depth distance, etc.). This preserves sharp edges by systematically looping through each pixel and adjusting weights to the adjacent pixels accordingly. Adobe Photoshop implements a bilateral filter in its surface blur tool. GIMP implements a bilateral filter in its Filters-->Blur tools; and it is called Selective Gaussian Blur'.The bilateral filter is defined aswhere the normalization termensures that the filter preserves image energy and is the filtered image; is the original input image to be filtered; are the coordinates of the current pixel to be filtered; is the window centered in is the range kernel for smoothing differences in intensities. This function can be a Gaussian function; is the spatial kernel for smoothing differences in coordinates. This function can be a Gaussian function;As mentioned above, the weight is assigned using the spatial closeness and the intensity difference. Consider a pixel located at which needs to be denoised in image using its neighbouring pixels and one of its neighbouring pixels is located at . Then, the weight assigned for pixel to denoise the pixel is given by:where σ_d and σ_r are smoothing parameters and I(i, j) and I(k, l) are the intensity of pixels and respectively.After calculating the weights, normalize them. where is the denoised intensity of pixel .".
