%LOAD_VOT_VIDEO_INFO
%   Loads all the relevant information for the video in the given path:
%   the list of image files (cell array of strings), initial position
%   (1x2), target size (1x2), the ground truth information for precision
%   calculations (Nx4, for N frames), and the path where the images are
%   located. The ordering of coordinates and sizes is always [y, x].
