Assignment #4, Question 11

To make an exact copy of the RB face of the colour cube on p. 404, you will need to enter the following octave command.

Octave command:

RB(:,:,1)=[ones(256,1)*[0:1:255]/255];
RB(:,:,2)=zeros(256);
RB(:,:,3)=[ones(256,1)*[0:1:255]/255]';
RB =rotdim(RB,270);

imshow(RB)



The rotdim function allows you to rotate the image so that the orientation of the RB face of the colour cube is the same as it appears in the textbook.
