im2single - Convert image to single precision
Syntax
I2 = im2single(I)
RGB2 = im2single(RGB)
I = im2single(BW)
X2 = im2single(X,'indexed')
Description
I2 = im2single(I) converts the intensity
image I to single, rescaling the data if necessary.
If the input image is of class single, the output image is identical
to it.
RGB2 = im2single(RGB) converts the truecolor
image RGB to single, rescaling the data if necessary.
I = im2single(BW) converts the binary image BW to
a single-precision intensity image.
X2 = im2single(X,'indexed') converts the
indexed image X to single precision, offsetting
the data if necessary.
Class Support
Intensity and truecolor images can be uint8, uint16, int16, single, double,
or logical. Indexed images can be uint8, uint16, double or logical.
Binary input images must be logical. The output
image is single.
Examples
I = reshape(uint8(linspace(1,255,25)),[5 5])
I2 = im2single(I)
