uint8
Convert an image to an uint8 image.

Synopsis

img = uint8( f )

Implemented in Python.

Input

f Image

Any image

Output

img Image Gray-scale uint8 image.

The converted image

Description

uint8 clips the input image between the values 0 and 255 and converts it to the unsigned 8-bit datatype.

Examples

>>> a = int32([-3,0,8,600])

              
>>> print uint8(a)

              
[  0   0   8 255]
