…endency.

• This should reduce the .jar sizes and speed up first-time model deployment
• To be checked:
  • @bmedicke : Mac still supported?
  • Did first-time deployment for others improve?

How to test:

git fetch
git checkout javacv-upgrade-and-optimizations-1.5
ant clean
ant run-debug

hi,
works on Win10 Laptop, first-time-deployment is a lot faster indeed...
(branch name needs prefix deinhofer: git checkout deinhofer/javacv-upgrade-and-optimizations-1.5)

Thanks for testing! Should be even more fast now. Split up architecture bundles into x86_64 and x86 on Windows.
When loading a service jar, the folowing file names are checked:

javacv-xxx-<os>-<architecture>-<bitness>.jar
javacv-xxx-<os>-<architecture>.jar
javacv-xxx-<os>.jar

• added proper error message dialog, if camera can't be opened.
• Made resizeHeight configurable, but this does not seem to have an impact --> probably remove property again
• The reason why the face detection occurs at a certain distance only is, that I used a MIN_FACE_WIDTH=80 and MIN_FACE_HEIGHT=80 which was fine for the master branch as well. The idea was to prevent face detection in the background of the image. Actually only faces closer to the camera will very likely be faces for camera mouse usage.

👍 , reduces loading time on my old PC from 5s to 1s:

This PR works just as well with macOS.

Tested on Win10, T470, Core-i7
First loading time of XCameraMouse: 2,2s (before with newer dependencies: 5s)
Instant face detection >100cm, before I needed to go closer to about 70cm

Made resizeHeight configurable, but this does not seem to have an impact --> probably remove property again

What is/was the intention of this property?

Actually only faces closer to the camera will very likely be faces for camera mouse usage.

Maybe it would be possible to limit the number of detected faces to 1 (if a face is already detected, do not detect another face). And if no face is detected the algorithm could start with a bigger minimum face size and decrease this property slowly, if no face is found. An easier solution maybe would be to just add a property "minFaceSize" which can be configured for a specific use case.

If tested again, as well:

I've started the ARE (on Windows) from terminal this time because there was no installer for this branch.

[deinhofer]

Ok, I will remove the resizeHeight property again and merge.
I will build the final installer tonight so that we can publish them tomorrow.
