manual tool - purpose of third window?

Post by korrupt78 »

Finally trying out the GUI in order to learn how to improve alignments for conversion, based on the guide in this subforum. I figured out how to navigate, adjust bounding boxes, and save, which is great - but I'm confused about the purpose of the third window.

What I mean is, when I run the manual tool from main GUI window, it pops up three new windows:
1) tall rectangle with keyboard shortcuts
2) large window with full size frame of video being worked on
3) wide rectangle with four adjacent boxes, and a thumbnail of the current frame in the left-most box (the other three are black)

I don't understand the purpose of that third window.

Still working on my first video (900 frames), realigned most of them manually already, but there are about a dozen that for some reason I can't make work.

Where ever on the face I click, the bounding box ends up being much smaller than I need. In 98% of cases I click around the mouth/nose area and it works perfectly, but for these dozen frames - which aren't even that different from the other ones - the box is much tinier, and I can't figure out how to expand it.

I see in the Help section that "middle click -> bounding box resize", but I can't figure out how that works. It just seems to produce nonsense when I try it...

Arg. Problem #3:

I just finished manually adjusting the alignment (or deleting the frame) across 900 frames (30s of video) and saved them. I then ran Extract to see the results as a set of images, and there's where I found surprises.

For example, when I'm in the Manual tool, if I'm looking at frame #213, I see the bottom half of a face correctly outlined by the boxes and points. (the top half isn't in this frame)

However, after Extract, the image file for frame #213 is just a forehead with some hair. Its almost as if its a completely different frame...

Arg. Problem #4.

In the meantime, decided to try converting the video using the work I'd already completed in the current version of my alignments file, to see how close I am.

Total fail. Almost every frame errored with something like:

02/12/2020 12:59:35 ERROR Failed to convert image: 'test_000130.png'. Reason: 'extended'


I'm pretty lost at this point.

Manual tool is being reworked. However:

It's a zoomed in box of the faces in the frame. If there are more than one face in the frame, the other boxes will fill. Just makes it easier to see on smaller faces
I see in the Help section that "middle click -> bounding box resize", but I can't figure out how that works. It just seems to produce nonsense when I try it...
Hold down the middle mouse button in the box and drag up/down to adjust the box height and left and right to adjust the box width.

Would need to see an example. Does this happen on every frame?

That looks like a bug. In the meantime, you can use the mask tool to re-generate the extended mask for your alignments file and it should fix it.
My word is final

Ok, with that understanding a little patience, I got that to work. I find it unintuitive - especially when the results lag a second or two behind the movement - but I see now how to carefully use it to improve landmark detection when the initial bounding box isn't appropriately sized or shaped. (left/down -> decrease dimension, right/up -> increase dimension)

It's especially weird when you drag left (to shrink width) which results in the left side of the box moving right. Feels wrong. :) Maybe at some point I'll dive into the code and change those bindings to arrow keys.

(Still working through the other issues.)

I wouldn't bother, It's being replaced with something much better,

Yeah, cv2 is a bit fiddly for that kind of thing, also was forced to use middle mouse button because of stupid cv2 default bindings.

Any guess when that'll be released? If it's really soon (days or weeks), it would make sense for me to avoid investing any more time practicing with and building on the existing tool and spend my time on other factors until the new tool arrives.

More likely weeks, but it will be released to Patreons first.
