# 1: standard approximation method, process blocks of level [4, 12],
# use up to 5 dictionary vectors
# 2: significantly increases the approximation quality,

# Quantization parameters define the accuracy of coefficients quantization.
# DC coefficients (of the constant dictionary vector f(x,y) = 1) are quantized
# to values of the interval [-`dc-rpf-range', `dc-rpf-range'] using

# motion compensated prediction is used.
# If 'cross-B-search' is set then the fast Cross-B-Search algorithm is
# used to determine the motion vectors of interpolated prediction. Otherwise
