2. export data gui

3. Can’t load data manually either

fPath = '~/Github/fex-metrica/fexSDK';

fexobj = fexc('data', fullfile(fPath,'samples','data','smile.csv'),...
'video',fullfile(fPath,'samples','data','smile.mov'),...
'outdir','~/Dropbox/Face/Tests/fexSDK_Test');

4. or using this method:

fPath = '/Github/fex-metrica/fexSDK';
data = dataset('File',fullfile(fPath,'samples','data','smile.csv'));
fexobj = fexc('data', data,...
'video',fullfile(fPath,'samples','data','smile.mov'),...
'outdir','/Dropbox/Face/Tests/fexSDK_Test');

and contains a "framnumber" column

Every method on fexwoverlay objects fails with the XLim problem.

FexObj = fexc('data', f{2});
d = FexObj.functional(1,13:15);
OvObj = fexwoverlay(d,'VarName',get(d,'VarNames'));
ii1 = fexwoverlay(d,'template','1','combine','max','background',0);

i1.show()

Paths are not clear, but I'm sure are subject to change.

1. fexfacetutil/cppdir -> fexfacetutil/preproc/cppdir
2. 'facet' -> FacetSDK/facets
3. 'fexfacetutil' -> fexfacetutil/preproc/install.sh

add capability to input cell array of filenames

The temp filter method from fexc calls the function fex_temporalfilter. Both have an argument "par," which is a vector with information about a filter. The issue is that the method expect to receive in "par" the sampling rate of the data. The function instead expects the nyquist frequency.

Unsync Timing issues:

1. The property .videoInfo is generated using ffmpeg. The time there is approximated so there may be a slight divergence between time assessed there and .time.TimeStamps(end). This should not be an issue.
2. The number of frames from .videoInfo and the size(f.functional,1) sometimes diverge, although usually of only few frames. This may be done to the procedures that look for frames with multiple faces (i.e. .checkargs).

Bugs

• Face Box identification and combination does not take into account missing faces, and it brakes when one frame don't contain a face.

Upgrade

• Instead of a single class with N entries per properties, it should be transformed into a stacked class;
• Add method to extract a frame at a particular time point with ffmpeg;
• Add codex / compression methods beyond mjpeg;
• Add box selection and resampling.
