In your data collection you gather a set of discrete fixation maps (P in the paper). From this, continuous saliency maps (Q in the paper) are generated. I found no details about how this is done, could you elaborate? I would guess that it involves gaussians centered on the spot of fixation, I am interested in the exact parameters, how you combine fixations from different test subjects and so on.

Thanks again for providing the dataset!

Hi,

First of all, thank you for providing such a nice dataset and code for evaluation metrics. I would like to evaluate my saliency results using five metrics that paper talked about.

I found that linear cross correlation can provide positive and negative values [-1,1]. So, when you present score for CC, did you take absolute value of each linear CC with respect to image and averaging it with each frame and each clip? Your MATLAB code doesn't do that, but that does make sense to me.

Look forward to your reply.

When using the evaluation code in this package, AUC-shuffled score is much lower than that reported in the paper on UCF dataset. I was wondering if it is anything wrong with the evaluation code, or if I missed some important details.

Hi, thanks for collecting such a valuable dataset! Several things I want to clarify with you:

1. I noticed they videos are with audios. Are the viewers accessible to them during the data collection?
2. As for the 1000 video clips, are they the complete clips that you directly downloaded from YouTube or you randomly cut some them from the raw videos?

Many thanks!

Did you use the whole fixation points when training and testing Hollywood2 dataset? Or, did you filter out some points? (e.x. filters out the points at image edge, ....) Also, did you use the whole 884 test videos when testing Hollywood2? How did you sync the fixation points with the video?

I am asking you this because I want to replicate the same result on Hollywood2 dataset. Could you provide a more detailed information of your setting? (I divided the videos by using shot bounds, as you mentioned)

You mentioned in a previous issue :

Hi, all, the data of Hollywood-2 and UCF have been uploaded.

The code (ACLNet) and dataset (DHF1K with raw gaze records, UCF-sports are new added!) can be downloaded from:

Is there also a link for the UCF-sports dataset?

Hi, I'm really interested in your work. And I used your training code -- 'ACL_full' to train my data. But during training, the loss always becomes NAN after several iterations: 53/100 [==============>...............] - ETA: 59s - loss: nan - time_distributed_15_loss: nan - time_distributed_16_loss: nan

I have tuned the base learning rate from 1e-4 to 1e-12, but the results are the same.

Do you know there are some solutions?

And what does the 'imgs_path' ('staticimages') in config.py mean?

Thanks very much!

Hi! Many thanks for your great work!

The ACL.h5 file could not be opened as a result of running the program. Is it possible that this file is corrupt?

Hi, thank you for your dataset and the source code, I wanna replicate this work with your code, but I am confused about the paths in config.py. I want to know what kinds of data has been used to train the model. In your paper Revisiting Video Saliency: A Large-scale Benchmark and a New Model ,you said that you have used the static dataset SALICON to train the attention module, and in your code there are several paths. Could you tell me:

• which paths are the video dataset's path and which is for the SALICON? Do you mean that frames_path is all the frames extracted from the video, and imgs_path is for the data in SALICON?
• do I need to extract all frames from the videos by myself?

related code are as follows:

# path of training videos
videos_train_paths = ['D:/code/attention/DHF1K/training/']
# path of validation videos
videos_val_paths = ['D:/code/attention/DHF1K/val/']
videos_test_path = 'D:/code/attention/DHF1K/testing/'

# path of training maps
maps_path = '/maps/'
# path of training fixation maps
fixs_path = '/fixation/maps/'

frames_path = '/images/'

# path of training images
imgs_path = 'D:/code/attention/staticimages/training/'

Thankyou.

Many thanks for your great work! as far as I can see, DHF1k_attribute.xlsx only provides data for the 300 test videos. Could you also provide this kind of attribute data for the first 700 videos? That would save me a lot of work and would be highly appreciated!

Hi, thanks for the nice dataset. I want to recreate the fixation maps using the raw gaze records in exportdata_train folder released for DHF1K.

However, the fixation map obtained using record_mapping.m script and raw data from exportdata_train folder donot match the ones released in DHF1K.

For example:

1. 0001.png: this is the fixation map for first frame of 001.AVI copied from: annotation/0001/fixation/0001.png

2. 0001_regenerated.png : I regenerated this fixation map using files from exportdata_train folder.

I used the record_mapping.m file after specifying appropriate paths and modifying line 22 and line 24.

Could you please help me understand what I might be missing?

For your reference, here is my copy of record_mapping.m file:
