  We present detailed characteristics of linear polarization features (LPFs) in
the quiet-Sun photosphere from high resolution observations obtained with
Sunrise/IMaX. We explore differently treated data with various noise levels in
linear polarization signals, from which structure and dynamics of the LPFs are
studied. Physical properties of the detected LPFs are also obtained from the
results of Stokes inversions. The number of LPFs, as well as their sizes and
polarization signals, are found to be strongly dependent on the noise level,
and on the spatial resolution. While the linear polarization with
signal-to-noise ratio $\geq4.5$ covers about 26% of the entire area in the
least noisy data in our study (with a noise level of $1.7\times10^{-4}$ in the
unit of Stokes $I$ continuum), the detected (spatially resolved) LPFs cover
about 10% of the area at any given time, with an occurrence rate on the order
of $8\times10^{-3}$ s$^{-1}$ arcsec$^{-2}$. The LPFs were found to be short
lived (in the range of $30-300$ s), relatively small structures (radii of
$\approx0.1-1.5$ arcsec), highly inclined, posing hG fields, and move with an
average horizontal speed of 1.2 km s$^{-1}$. The LPFs were observed (almost)
equally on both upflow and downflow regions, with intensity contrast always
larger than that of the the average quiet-Sun.
