The Extended Cohn-Kanade (CK+) database distribution: PHASE 1
Initial: 1st July 2010
Revised: 28th Sept 2010
---------------------------------------------------------------------------------------
In this Phase there are 4 zipped up files. They relate to:
1) The Images (cohn-kanade-images.zip) - there are 593 sequences across 123 subjects which are FACS coded at the peak frame. All sequences are from the neutral face to the peak expression.
2) The Landmarks (Landmarks.zip) - All sequences are AAM tracked with 68points landmarks for each image.
3) The FACS coded files (FACS_labels.zip) - for each sequence (593) there is only 1 FACS file, which is the last frame (the peak frame). Each line of the file corresponds to a specific AU and then the intensity. An example is given below.
4) The Emotion coded files (Emotion_labels.zip) - ONLY 327 of the 593 sequences have emotion sequences. This is because these are the only ones the fit the prototypic definition. Like the FACS files, there is only 1 Emotion file for each sequence which is the last frame (the peak frame). There should be only one entry and the number will range from 0-7 (i.e. 0=neutral, 1=anger, 2=contempt, 3=disgust, 4=fear, 5=happy, 6=sadness, 7=surprise). N.B there is only 327 files- IF THERE IS NO FILE IT MEANS THAT THERE IS NO EMOTION LABEL (sorry to be explicit but this will avoid confusion).
Examples:
-----------------------------------------------------------------------------------
All file name and structure should be the same. For example, an image
at:
cohn-kanade-images/S005/001/S005_001_00000011.png
------------------------------------------------------------------------------------
will have the corresponding landmark at:
Landmarks/S005/001/S005_001_00000011_landmarks.txt
------------------------------------------------------------------------------------
FACS code at:
FACS/S005/001/S0005_001_00000
