function [ds, bs] = process(im, model, thresh)
% Detect objects that score above a threshold.
%   [ds, bs] = process(im, model, thresh)
%
%   If the threshold is not included we use the one in the model.
%   This should lead to high-recall but low precision.
%
% Return values
%   ds        Clipped detection windows
%   bs        Boxes for all placed filters
%
% Arguments
%   im        Image
%   model     Object model
%   thresh    Detection threshold
