Can you offer some samples about manual attribute?
I am wondering how you annote mannual attribute on the video, can you give me some hints?
I think UCF101 dataset come along with manual attribute description. I'm not sure of the format they used, in order to be used as semantic embeddings. I would like to know about it.
I believe UCF101 is available here: http://www.thumos.info/download.html Regarding the attributes for the Olympic dataset, I think it was in some pdf file. https://github.com/gzoumpourlis/olympic_sports_tools The pdf is linked there.
Thanks, @devraj89 , there are the manual attributes, but what is word2vec attributes?
Is it possible to define manual attributes for the hmdb51 dataset? if yes, can you describe how? Thank you very much.
@fjchange the word2vec attributes are generated by sending the category names through the word2vec model. @GayatriPurandharT I really do not know how the manual attributes were even constructed for the other two datasets. I just used the ones that were provided to us. Maybe you can ask the original authors regarding how they generated the attributes ? This might itself be a research topic.
@devraj89 Thanks for your reply. I downloaded attributes provided by UCF101. Each action has got attributes with truth-value 0/1. Can I add a new action of my own? I would want to know how the video features and attributes have been merged into data_action/ucf101/split_1/att_splits.mat can. So that I train my own videos with new actions. Thanks
@GayatriPurandharT regarding adding new action classes I am not sure. You have to figure out what the attributes should be. As I mentioned previously, contact the original authors of UCF101 dataset. They might be able to tell you on this more.
att_splits.mat --> for this please go through this paper : https://arxiv.org/abs/1712.00981 and the code: https://www.mpi-inf.mpg.de/departments/computer-vision-and-machine-learning/research/zero-shot-learning/feature-generating-networks-for-zero-shot-learning/ to understand how the .mat file was created.
To generate those files I had to write a separate code which I dont have access to right now.
@devraj89 Thanks a lot for the information. I will go through the code. Also, it would be really helpful if you publish the code to create .mat files for video files and attributes.
@GayatriPurandharT : Were you able to create attributes file for UCF 101 ? If yes, can you please share it ? Please also share the code to create the files if you have it.
