idouble

Convert integer image to double

imd = idouble(im) is an image with double precision elements in the range 0 to 1 corresponding to the elements of im. The integer pixels im are assumed to span the range 0 to the maximum value of their integer class.

Notes

• Works for an image with arbitrary number of dimensions, eg. a color image or image sequence.
• There is a linear mapping (scaling) of the values of IMD to IM.
