Evaluate_anomaly_detector.m- C3D features for videos (.fc file) what's this .fc files

[cervantes-loves-ai]

i was trying to run your Evaluate_anomaly_detector.m file but you mentioned there that for C3D_CNN_Path case needed to put .fc files there but how to get that .fc files

and got error like this

ivideo =

 1

Undefined variable "Annotation_file" or class "Annotation_file.VideoName".

Error in Evaluate_Anomaly_Detector_RoadAccident (line 33)
check=strmatch(All_Videos_scores(ivideo).name(1:end-6),Annotation_file.VideoName(1:end-3));

[cervantes-loves-ai]

now got this error

ivideo =

 1

Array indices must be positive integers or logical values.

Error in Evaluate_Anomaly_Detector_another_CLG (line 85)

Hi, please take a look at Script folder and C3D feature extraction notebook in this repo.

[cervantes-loves-ai]

when tried to extract feature from C3DV0.ipynb got this error

Make sure that you are using GColab under the GPU mode. Also, carefully prepare the necessary input files for C3D feature extraction (visit Facebook C3D repo and Document link on the README description).

i will check, thank you. is it possible to share .fc files, because last time you shared filed regarding to c3d feature extractor but in that folder .fc files was missing. i just want to test Evaluate_anomaly_detector.m . thanks in advance.

[dolongbien]

I can share *.fc6 files but the thing is that Evaluation code also needs corresponding mp4 video of that fc6 (which I could not share at the moment). Anyways, I will send you some for you to experiment.

[cervantes-loves-ai]

thank you so much.

[dolongbien]

Here is the OneDrive link of 15 testing videos (mp4 and fc-6). Hope this help!
