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.
