Convert image to uint16.
The conversion of img to a 16-bit unsigned integer, is dependent on the type of input image. The following input classes are supported for non-indexed images:
Values are rescaled to the range of the uint16 class [0 65535].
True and false values are assigned a value of 0 and 255 respectively.
Values are truncated to the interval [0 1] and then rescaled to the range of values of the int16 class [0 255].
Returns the same image.
If the second argument is the string "indexed", then values are
cast to uint16, and a -1 offset is applied if input is
a floating point class. Input checking is performed and an error will
be throw is the range of values in uint16 is not enough for all the
image indices.
