Hi, you are correct. Gaussian filter is not an ideal low-pass filter so it can't filter high-frequency components completely. Will change the description to make it more clear. Thanks for the correction.
Thank you!
Thanks your great work!
One question: In the last paragraph in
5.1 3D Smoothing Filter
, "By employing 3D Gaussian smoothing, we ensure that the highest frequency component of any Gaussian does not exceed half of its maximal sampling rate for at least one camera."As I know, gaussian filter is soft smoothing filter, so most high frequency ($> \hat v_k/2$) component of a gaussian will be remove, but still very little high frequency ($> \hat v_k/2$) component will remain . Am I corret?
In one word: No any high frequency($> \hat v_k/2$) component remain, or still very little high frequency($> \hat v_k/2$) component remain?
