THUMOS feature extraction

[thematrixduo]

Could you please share how do you obtain the extracted features for THUMOS dataset? Also for TSN models using ResNet-50, the final feature maps has depth 2048. However in your h5 file the feature has 1024 dims. How do you obtain this? Many Thanks!

Hi, I think It combine Flow.h5 and RGB.h5, so the feature maps has depth 2048.

Hi, I think It combine Flow.h5 and RGB.h5, so the feature maps has depth 2048.

In the code, they actually concatenate the two features, resulting in a vector of 2048 dims. However the raw feature vector from Flow and RGB only has 1024 dims. This is different from the official TSN model.
