FAP BAP blender - isir/greta GitHub Wiki

FAP/BAP blender

In order to use multiple behavior generators in parallel, we created FAP/BAP blenders.

  • Since this modules assume the input signals are two, you need to cascade blenders to blender signals more than three.
  • When you connect modules, you need to specify the corresponding input node names (check the following screenshot as an example).
  • You must assign different node name for each input signal otherwise it does not work properly.
  • Please note that the names can be different for each blender.

Greta has the following frame-level representations:

  • FAPFrame: frame-level representation of facial expressions
  • BAPFrame: frame-level representation of body expressions

For FAPFrame, we implemented the following blenders:

  • LipBlender
  • FaceBlender

For BAPFrame, we implemented the following blenders:

  • BodyBlender

For more details, please check the following implementation files:

  • LipBlender: greta\core\MPEG4\src\greta\core\animation\mpeg4\fap\filters\LipBlender.java
  • FaceBlender: greta\core\MPEG4\src\greta\core\animation\mpeg4\fap\filters\FaceBlender.java
  • BodyBlender: greta\core\MPEG4\src\greta\core\animation\mpeg4\bap\filters\BodyBlender.java
