1. A method for determining at least one dominant eye of a user for the task of gaze estimation, the method comprising:
1) obtaining at least one frame of a digital image of a user;
2) detecting at least one of a face, an eye region, or a head pose within the at least one frame using at least one first convolutional neural network applied to at least one data matrix; and
3) determining the user's dominant eye based on an extracted portion of the at least one of a face, an eye region, or a head pose, wherein the extracted portion includes left and right eye patches of the digital image of the user;
and wherein the user's dominant eye is determined by applying at least one second convolutional neural network to the left and right eye patches of the digital image of the user.
