A research project for facial expression detection by utilizing state of the art depp convultional neural networks.
Currently we are replacing every occurrence of 0 in the image with the mean, converting every black pixel to a mean pixel. This obviously also changes the color of pixels that are not part of the mask.
Possible solution:
According to BVLC/caffe#1470 HDF5 files must not be larger than 2GB unzipped.
We should add this constraint to our extract_frames.py
script.
Store frames/flow data in HDF5 format
We only have labels 0 or 1 for each class depending on its prediction. There are never going to be negative values. We might need to threshold on 0.5 since we probably get probabilities.
We need to split our data into train and test. Script should read the "filaname label".txt and split it according to a parameter into two such files.
We are in general very short on training examples. Therefore we should generate new ones based on existing ones:
Currently we are generating a separate hdf5 db for x and for y flows. That doesn't make too much sense since we need them in one. They should be stacked in alternating order (x1, y1, x2, y2,...) to get a 20 channel blob.
