recover floating point values from quantized data


unu unquantize -i,--input <nin> [-min,--minimum <value>] [-max,--maximum <value>] [-double] [-o,--output <nout>]


Recover floating point values from quantized data. Uses the oldMin and oldMax fields in the nrrd of quantized values to regenerate approximate versions of the original unquantized values. Can also override these with “-min” and “-max”.


-i <nin> , --input <nin>

input nrrd. That this argument is required instead of optional, as with most unu(1) commands, is a quirk caused by the need to have unu-unquantize(1) generate usage info, combined with the fact that all the other arguments have sensible defaults.

-min <value> , --minimum <value>

Defaults to nin->oldMin if it exists, otherwise 0.0 (double)

-max <value> , --maximum <value>

Defaults to nin->oldMax if it exists, otherwise 1.0 (double)


If not using “-min” or “-max”, whether to know the range of 8-bit data blindly (uchar is always [0,255], signed char is [-128,127]) (bool); default: “true”, "true"

-o <nout> , --output <nout>

output nrrd (string); default: “-
