Nettet17. nov. 2024 · A black pixel in its neighborhood will have more weight than a white one, because of $ I_p-I_q $, which is not the case in standard linear filtering. For Question 1 , the choice really depends on the scale of objects ( $\sigma_S$ ) and the range of intensities ( $\sigma_r$ ) you want to preserve, and this is domain dependent.

Nettet25. sep. 2024 · Bilateral filter is image filter that varies sample weights not only based on image-space distance in pixels, but also the similarity between color samples. In an equation form this could be written as: y = Sum (w (x, xij) * xij) / Sum (w (x, xij) w (x, xij) = wx (i,j) * wy (x, xij) Where wx is spatial weight, and wy is signal similarity weight ...
