         Human Actions and Scenes Dataset
   


We provide a dataset with 12 classes of human actions and 10 classes 
of scenes distributed over 3669 video clips and approximately 20.1 hours 
of video in total. The dataset intends to provide a comprehensive 
benchmark for human action recognition in realistic and challenging 
settings. The dataset is composed of video clips from 69 movies 
(see the list of movies below). A part of this dataset was originally 
used in the paper "Actions in Context", Marszalek et al. in Proc. CVPR'09.
	

Action samples were collected by means of automatic script-to-video 
alignment in combination with text-based script classification following 
Laptev at al. CVPR'08. Video samples generated from training movies 
correspond to the automatic training subset with noisy action labels. 
Based on this subset we also constructed a clean training subset with 
action labels manually verified to be correct. We also provide a test 
subset with manually checked action labels.

Scene classes are selected automatically from scripts such as to maximize 
co-occurrence with the given action classes and to capture action context 
as described in Marsza?ek et al. CVPR'09. Scene video samples are then 
generated using script-to-video alignment. The labels of test scene 
samples are manually verified to be correct.

The following tables provide the numbers of video samples in each of the 
subsets as well as the distributions of class instances in each subset. 
Note that samples may contain instances of several actions such e.g. 
kissing and hugging.

================

The dataset is split in two parts with actions and scene samples respectively:

(approx. size: 15Gb | md5sum: 55948d0ef45a569a2134ea44e6f8976c)

(approx. size: 25Gb | md5sum: b77f9ffe18ad5ea04957bb4c7725f5ce)

Action video samples are provided in directory AVIClips for three subsets 
according to the table above. The annotation of samples w.r.t. 12 action classes
is located in ClipSets directory. Similarly, the video samples and annotations 
for scene samples are located in AVSClipsScenes and ClipSetsScenes directories 
respectively.
	
Example:
The file ClipSets/AnswerPhone_autotrain.txt contains annotation for AnswerPhone 
action in the automatic training subset with 810 video clips. Each line of the 
annotation file provides a name of a video sample in AVIClips directory as well 
as the flag = {1|-1} indicating whether the sample contains AnswerPhone or not. 
(Our annotation format is similar to PASCAL VOC annotation format for image 
classification task).

We also provide conditional probability tables

movie scripts and used in "Actions in Context" Marszalek et al. CVPR'09 paper:
