about "filtering depth maps" process steps, even it's disabled.

Hi everyone,

Could anyone let me know what PhotoScan exactly do "filtering depth mapping" on the step of "build dense cloud"?

I'm curious that, even "Depth filtering" option is disabled in the advanced option for Build dense cloud, "filtering depth maps... done in xxx.xx sec" message is logged on the Console.

And I don't really understand the processing time.
Between depth filtering option by "aggressive" and "disabled", aggressive is faster.

Doesn't it do nothing when the depth filtering is set to "disabled"?
Why "aggressive" has done it faster than "disabled"?

--
Aggressive  >> filtering depth maps... done in 158.518 sec
Disabled      >> filtering depth maps... done in 104.74 sec

Tested conditions as below:
-PhotoScan Professional Ver 1.2.4 (Build 2399)
-Unchecked "keep depth maps" on advance tab in Preferences.
-disabled/ aggressive type on advance option in Build Dense Cloud.
-OpenCL is enabled.


Thanks for any advices!
Toshi
