Hey Alexey, can you explain what Generate Defocus Masks is?
Also very interested to know what this does and how it works.
Thanks,
JRP
Hi jrp,
I did some tests with this feature and it creates a mask in out-of-focus areas of the image. It seems to be similiar to Photoshops "Focus Area" tool, where based on local contrast etc. blurred parts are masked but it seems to be more sophisticated since you require a scaled model for the mask to work.
The results are great and this is super useful for creating textures without having to deal with out-of-focus areas being mapped to the texture.
This could also be useful when working with small objects where depth of field is always a problem: Create a rough, scaled model with all images, run the filter, realign with created masks (excluding feature detection on masked areas) and then running the high-res reconstruction. But I'm sure Alexey will clarify the use cases.
Thanks Agisoft team! Great update <3
