im2int16

Convert image to 16-bit signed integers

Syntax

• I2 = im2int16(I)
  RGB2 = im2int16(RGB)
  I = im2int16(BW)
  

Description

im2int16 takes an image as input and returns an image of class int16. If the input image is of class int16, the output image is identical to it. If the input image is not of class int16, im2int16 returns the equivalent image of class int16, rescaling or offsetting the data as necessary.

I2 = im2int16(I) converts the intensity image I to int16, rescaling the data if necessary.

RGB2 = im2int16(RGB) converts the truecolor image RGB to int16, rescaling the data if necessary.

I = im2int16(BW) converts the binary image BW to an int16 intensity image, changing false-valued elements to -32768 and true-valued elements to 32767.

Class Support

Intensity and truecolor images can be uint8, uint16, int16, single, double, or logical. Binary input images must be logical. The output image is int16.

Example

• I = reshape(linspace(0,1,20),[5 4])
  I2 = im2int16(I)
