OpenCV-webcam-demo (c++)
------------------

Project for demoing the [FrameDetector class](https://knowledge.affectiva.com/docs/analyze-a-video-frame-stream-3). It grabs frames from the camera, analyzes them and displays the results on screen.

The following command line arguments can be used to run it:

    -h [ --help ]                        Display this help message.
    -d [ --data ] arg (=data)            Path to the data folder
    -r [ --resolution ] arg (=640 480)   Resolution in pixels (2-values): width
                                         height
    --pfps arg (=30)                     Processing framerate.
    --cfps arg (=30)                     Camera capture framerate.
    --bufferLen arg (=30)                process buffer size.
    --cid arg (=0)                       Camera ID.
    --faceMode arg (=0)                  Face detector mode (large faces vs small
                                        faces).
    --numFaces arg (=1)                  Number of faces to be tracked.
    --draw arg (=1)                      Draw metrics on screen.

Video-demo (c++)
----------

Project for demoing the Windows SDK [VideoDetector class](https://knowledge.affectiva.com/docs/analyze-a-recorded-video-file) and [PhotoDetector class](https://knowledge.affectiva.com/docs/analyze-a-photo-4). It processs video or image files, displays the emotion metrics and exports the results in a csv file.

The following command line arguments can be used to run it:

    -h [ --help ]                        Display this help message.
    -d [ --data ] arg (=data)            Path to the data folder
    -i [ --input ] arg                   Video or photo file to process.
    --pfps arg (=30)                     Processing framerate.
    --draw arg (=1)                      Draw video on screen.
    --faceMode arg (=1)                  Face detector mode (large faces vs small
                                         faces).
    --numFaces arg (=1)                  Number of faces to be tracked.
    --loop arg (=0)                      Loop over the video being processed.
