Align Photos Accuracy Search Range???

[workerb]

Ok, so I believe the search range for setting for Worklfow/Build Geometry/Target Quality are:

Ultra High - Every 2nd pixel in image
High - Every 4th pixel in image
Medium - Every 8th pixel in image
Low - Every 16th pixel in image

But what is the search range for Workflow/Align Photos/Accuracy
High???
Medium???
Low???

 

[FoodMan]

thought ultra high would use every pixel....?

[Wishgranter]

Yes, ultra is every pixel.......

Ok, so I must have been mistaken.

ULTRA - 1x1 px
HIGH - 2x2 px
MEDIUM - 4x4 px
LOW - 8x8 px
WLOW - 16x16 px....

But what is the search range for Workflow/Align Photos/Accuracy
High???
Medium???
Low???

Hello workerb,

But what is the search range for Workflow/Align Photos/Accuracy
High???
Medium???
Low???

It's similar to Build Geometry stage 1, 2, 4.
Additionally for low-resolution images the gradation is different in 0.9.1: High accuracy uses upscaled images (by factor 2), Mediuim - origianl images, Low - downscaled by 2.

Thanks Alexey.

When you say "low-resolution images", what resolution do you mean? Where are the limits between low and high resolution here?

Good information! Thanks for posting this.

Hello RalfH,

Images with resolution lower than 5 MPix will have one extra-accuracy (High -> Ultra High) step on Align Photos stage.
Mostly it was implemented for thermal images.

Ok, thanks!
