Hi Dan,<BR>
<BR>
thanks for sharing your results. VHGW indeed looks good here. Next week I will try again at my machine and make sure windows is not secretly running other programs while I run my test.<BR>
<BR>
Thanks for all the feedback,<BR>
<BR>

Hi Marius,<BR>
<BR>
Thanks for providing your code. I ran it with the following:<BR>
ITK 3.12<BR>
CMake 2.6.2<BR>
Visual Studio 8.0.50727.867<BR>
Windows Vista SP1<BR>
2 x 2 GHz, 3 GB RAM<BR>
Release build<BR>
<BR>
The results were as follows:<BR>
<BR>
Box radius: 1<BR>
Elapsed time erosion_binary: 6.558s.<BR>
Elapsed time erosion VHGW: 6.177s.<BR>
Elapsed time erosion Anchor: 44.742s.<BR>
Box radius: 2<BR>
Elapsed time erosion_binary: 7.068s.<BR>
Elapsed time erosion VHGW: 6.114s.<BR>
Elapsed time erosion Anchor: 42.208s.<BR>
Box radius: 4<BR>
Elapsed time erosion_binary: 8.595s.<BR>
Elapsed time erosion VHGW: 6.199s.<BR>
Elapsed time erosion Anchor: 44.865s.<BR>
Box radius: 8<BR>
Elapsed time erosion_binary: 14.707s.<BR>
Elapsed time erosion VHGW: 6.46s.<BR>
Elapsed time erosion Anchor: 44.666s.<BR>
Box radius: 16<BR>
Elapsed time erosion_binary: 38.651s.<BR>
Elapsed time erosion VHGW: 7.117s.<BR>
Elapsed time erosion Anchor: 46.104s.<BR>
Box radius: 32<BR>
Elapsed time erosion_binary: 125.506s.<BR>
Elapsed time erosion VHGW: 7.656s.<BR>
Elapsed time erosion Anchor: 49.61s.<BR>
<BR>
These results match with my previous experience with the VHGW filter:<BR>
constant time, very fast. Thanks again Richard and Gaëtan!!<BR>
<BR>
Marius: I hope this helps.<BR>
<BR>
Regards, Dan<BR>
