2022-11-01tracker/nn: Tweaks, refactoring, a deadzone filtering and support for ↵Michael Welter
uncertainty estimation * Add rudimentary test for two functions .. maybe more in future * Fix the rotation correction from vertical translation * Move preview class to new files * Move neural network model adapters to new files * Add utility functions for opencv * Query the model inputs/outputs by name to see what is available * Supports outputs for standard deviation of the data distribution - What you get if you let your model output the full parameters of a gaussian distribution (depending on the inputs) and fit it with negative log likelihood loss. * Disabled support for sequence models * Add support for detection of eye open/close classification. Scale uncertainty estimate up if eyes closed * Add a deadzone filter which activates if the model supports uncertainty quantification. The deadzone scales becomes larger the more uncertain the model/data are. This is mostly supposed to be useful to suppress large estimate errors when the user blinks with the eyes * Fix distance being twice of what it should have been
