DAHLIA (DAily Human Life Activity)

DAHLIA dataset is devoted to human activity recognition, which is a major issue for adapting smart-home services such as user assistance.

DAHLIA has been realized in Mobile Mii Platform by CEA LIST, and has been partly supported by ITEA 3 Emospaces Project (

DALHIA has been published at the 12th IEEE Conference on Automatic Face & Gesture Recognition, Washington DC, USA, May 31th – 3rd June, 2017. See Paper here

Videos were recorded in realistic conditions, with 3 Kinect v2 sensors located as they would be in a real context. The long-range activities were performed in an unconstrained way (participants received only few instructions), and in a continuous (untrimmed) sequence, resulting in long videos (40 min in average per subject). Contrary to previously published databases, in which labeled actions are very short and have low-semantic level, this new database focuses on high-level semantic activities such as « Preparing lunch » or « House Working ».

DAHLIA Datafile Package:

The dataset is devided into two sets:
– set1: 25 examples
– set2: 26 examples

The tree structure and content of directories is done as below:


In a set, examples are ordered by subject and acquisition number.
In each examples, you will find the directories for each stream of the three cameras and the Label directory which is common to all views.

  • Label : The xml files with activity label for each frames.
    Activities are : Cooking (id: 1) – Laying table (2) – Eating (3) – Clearing Table (4) – Washing dishes (5) – Housework (6) – Working (7) – Neutral (0)
  • Color : The RGB avi video file
  • Depth : The jpg2000 files corresponding to depth map
  • Time : The timestamp files
  • Body : The csv files with skeleton 3D coordinates.
    Fileskeleton.csv: expressed in depth map referential. FileskeletonSkSpace.csv: expressend in real world referential.
  • BodyIndex.7z : (when extracted,) The body index binaries files which can be decoded in tif files thanks to the C++ software:
    You will then obtain a black and white image correponding to the body index returned by the Kinect v2.
