Grouth-truth AU heatmap generation #5

Hi @ESanchezLozano , Is it possible to upload the code of generating the ground-truth AU heatmap?

I am trying to implement your code to generate ground-truth AU heatmap, but did not find it in this repository. (I am not quite sure about equation 1 in the paper: why i, j should be smaller or equal to 6*Intensity?)

Thanks a lot!

Hi,

Unfortunately, I am not allowed to disclose the training code. However, here's a hint: you can build upon the code for heatmap regression for facial landmark localisation (FAN). Just check how the Gaussian is created to incorporate the elements that are mentioned in the paper ;)

The use of 6 is to basically limit the Gaussian when generating the heatmaps, but technically it can go as far as you wish using the exponential values. Nothing will happen if you do so :)

Hope this helps :)

Hi, Do you use any mapping from facial landmarks to action units to find the centers of action units? If so, can you direct me to some papers or resources where I can find such mappings? Thank you very much in advance.
