Open Live Script

Read the pixel values from an image as 16-bit unsigned integers. 

I = im2uint16(imread("peppers.png"));
whos I
  Name        Size                 Bytes  Class     Attributes

  I         384x512x3            1179648  uint16

Convert the pixel values to half-precision. The half-precision values are stored as data type single.

I2 = exrHalfAsSingle(I);
whos I2
  Name        Size                 Bytes  Class     Attributes

  I2        384x512x3            2359296  single

Input Arguments

collapse all

Input data, specified as a numeric array or a cell array of numeric arrays.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | cell

Output Arguments

collapse all

Output data, returned as a numeric array or a cell array of numeric arrays. If I is a numeric array, then out is an array the same size as I of data type single. If I is a cell array, then out is a cell array the same size as I in which each element is an array the same size as the corresponding element of I, of data type single.
