C3D-tensorflow

Requirements:

  1. You must have installed the following two python libs: a) tensorflow b) Pillow
  2. You must have downloaded the UCF101 (Action Recognition Data Set)
  3. Each single avi file is decoded with 5FPS (it's depend your decision) in a single directory.
    • you can use the ./list/convert_video_to_images.sh script to decode the ucf101 video files
    • run ./list/convert_video_to_images.sh .../UCF101 5
  4. Generate {train,test}.list files in list directory. Each line corresponds to "image directory" and a class (zero-based). For example:
    • you can use the ./list/convert_images_to_list.sh script to generate the {train,test}.list for the dataset
    • run ./list/convert_images_to_list.sh .../dataset_images 4, this will generate test.list and train.list files by a factor 4 inside the root folder

  1. If you want to test my pre-trained model, you need to download my model from here: https://www.dropbox.com/sh/8wcjrcadx4r31ux/AAAkz3dQ706pPO8ZavrztRCca?dl=0

Run command:

  1. python train_c3d_ucf101.py will train C3D model. The trained model will saved in models directory.
  2. python predict_c3d_ucf101.py will test C3D model on a validation data set.

Experiment result:

Top-1 accuracy of 72.6% should be achieved for the validation dataset with this code and pre-trained from the sports1M model. You can download my pretrained UCF101 model and mean file from here: https://www.dropbox.com/sh/8wcjrcadx4r31ux/AAAkz3dQ706pPO8ZavrztRCca?dl=0
