Parameters

img	An image structure
max_n_peaks	The maximum number of peaks to be searched for
threshold	The image threshold value, in detector units
min_snr	The minimum signal to noise ratio for a peak
min_pix_count	The minimum number of pixels in a peak
max_pix_count	The maximum number of pixels in a peak
local_bg_radius	The averaging radius for background calculation
min_res	The minimum number of pixels out from the center
max_res	The maximum number of pixels out from the center
use_saturated	Whether saturated peaks should be considered

Runs the peakfinder8 peak search algorithm
