Can anyone help me out? How to change my input image data in grayscale 257x251x1 uint8 change into 'truecolor' rgb type? (mxnx3)
Here my codes:
I=imread('1222.png');
I2=I(:,:,1:3);
The error occured; Index in position 3 exceeds array bounds (must not exceed 1).

Based on the sizes it looks like you concatenated along the first dimension when you needed to concatenate along the 4th dimension.
