im2uint8 — Convert image data to uint8 using image scaling rules.

im2uint8(I) converts floating image values in [0,1] to uint8 [0,255] and rescales uint16 image data.

How im2uint8 works

• Floating-point inputs are clamped to [0,1], multiplied by 255, and rounded.
• uint16 inputs are rescaled from [0,65535] to [0,255].

Example

Convert Double Image

J = im2uint8(I);

Expected output:

% J is uint8 image data
