-------------------------------------------------------------------------------------- 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_00000011_facs.txt which has 9.0000000e+00   4.0000000e+00 1.7000000e+01   2.0000000e+00 this means that AU9d and AU17b are present N.B if an AU is present but the intensity is 0 this means that the intensity was not given e.g. 1.20000000e+00 0.000000000e+00 just means AU12 (intensity not given). ------------------------------------------------------------------------------------ Emotion code at: Emotion/S005/001/S005_001_00000011_emotion.txt which has 3.00000000e+00 that is disgust -------------------------------------------------------------------------------------- Soon we will release Phase 2 which will contain the non-posed smiles portion of the dataset. Phase 3 will contain the non-frontal synchronous data. Please see website for updates. For full details see: P. Lucey, J.F. Cohn, T. Kanade, J. Saragih, Z. Ambadar and I.
