action units maps extraction
hi,
can you please confirm that gh2
is the attention maps?
Line 53 in 0bfb778
it is of size (batch_size, 12, 12, number_action_units)
. here, number_action_units=12
.
attention maps are output of the arrow in this fig.3 from https://openaccess.thecvf.com/content/CVPR2021/papers/Jacob_Facial_Action_Unit_Detection_With_Transformers_CVPR_2021_paper.pdf
when plotting one of the attention maps, i am supposed to see something similar to fig1, right?
i run python inference.py
and extracted gh2
. i plotted all gh2[0, :, :, i] for i in range(12), right to the image. but i am seeing something strange.
below are the plots from 0 to 11.
here are the unique values per map:
map: 0: [1.]
map: 1: [0. 0.9982668 1. ]
map: 2: [0. 1.]
map: 3: [1.]
map: 4: [0.]
map: 5: [0. 1.]
map: 6: [1.]
map: 7: [0.]
map: 8: [0.]
map: 9: [0.0000000e+00 2.0861626e-07 9.4047523e-01 1.0000000e+00]
map: 10: [0.]
map: 11: [0.]
also strange. the sigmoid could be doing this. but with or without sigmoid, i am supposed to get attentions that point to rois.
can you help? i may be missing something.
can you show how did you plot attentions in fig1?
very much appreciated.
thanks
Testing with webcam
I tried inference model with webcam BGR input frame, use SCRFD to detect face then crop and convert to GRAY image before feed to the FAU model but the prediction is not consistent with my movement. Could you please share the correct way to preprocess image?
Recurring problems
Hello, thank you for your code contribution. Could you please send me the final code? I cannot reproduce this code, because there are many undeclared variables in the code.
