The extensive database of high-resolution G-band images observed with theHinode/SOT is a unique resource to derive statistical properties of pores usingadvanced digital image processing techniques. The study is based on two datasets: (1) Photometric and morphological properties inferred from single G-bandimages cover almost seven years from 2006 October 25 to 2013 August 31. (2)Horizontal flow fields have been derived from 356 one-hour sequences of G-bandimages using LCT for a shorter period of time from 2006 November 3 to 2008January 6 comprising 13 active regions.  A total of 7643/2863 (single/time-averaged) pores builds the foundation ofthe statistical analysis. Pores are preferentially observed at low latitudes inthe southern hemisphere during the deep minimum of solar cycle No. 23. Thisimbalance reverses during the rise of cycle No. 24, when the pores migrate fromhigh to low latitudes. Pores are rarely encountered in quiet-Sun G-band images,and only about 10% of pores exists in isolation. In general, pores do notexhibit a circular shape. Typical aspect ratios of the semi-major and -minoraxes are 3:2 when ellipses are fitted to pores. Smaller pores (more thantwo-thirds are smaller than 5~Mm^2) tend to be more circular, and theirboundaries are less corrugated. Both area and perimeter length of pores obeylog-normal frequency distributions. The frequency distribution of the intensitycan be reproduced by two Gaussians representing dark and bright components.Bright features resembling umbral dots and even light-bridges cover about 20%of the pore's area. Averaged radial profiles show a peak of the intensity atnormalized radius R_N = r /R_pore = 2.1, followed by maxima of the divergenceat R_N= 2.3 and the radial component of the horizontal velocity at R_N= 4.6.The divergence is negative within pores.
