FIELD: physics.
SUBSTANCE: in compliance with this method, binary image of initial image fragments is generated by linear convolution with the help of spatial filter, its core including central and peripheral parts. Note here that linear convolution is conducted separately with spatial filter central core and linear parts. Major components used as binary images of initial image fragments are constructed wherein spatial filter central part features an exponential shape. Note also that peripheral part has negative factors and is constructed with the help of exponent proceeding from the sum of said central and peripheral parts being zero.
EFFECT: higher quality.
