# how to convert grey image to RGB?

i have 60 slice grey image. how want to convert to RGB image?

as attached is my grey image (grey.jpg). rgb.jpg is from internet what i want like.

this is my coding, but got error.

`P = zeros(103, 103, 60);for K = 1 : 60    K_file=30+10*K;    petname = sprintf('I%d.dcm', K_file);    P(:,:,K) = dicomread(petname);         scale = 130/103 ; Pi(:,:,K) = imresize(P(:,:,K),scale) ; % where P is your 103*103 3D matrix endrgbImage = gray2rgb(Pi);imshow3D(rgbImage)`

this is my function

`function [Image]=gray2rgb(Image)%Gives a grayscale image an extra dimension%in order to use color within it[m n]=size(Image);rgb=zeros(m,n,3);rgb(:,:,1)=Image;rgb(:,:,2)=rgb(:,:,1);rgb(:,:,3)=rgb(:,:,1);Image=rgb/255;end`

BUT GOT ERROR.

`Unable to perform assignment because the size of the left side is 130-by-7800 and the size ofthe right side is 130-by-130-by-60.Error in gray2rgb (line 6)rgb(:,:,1)=Image;Error in sliderspect1 (line 12)rgbImage = gray2rgb(Pi);`

Your Pi is a [130 x 130 x 60] matrix, but your function gray2rgb() expects a 2D matrix as input. It is not clear how you want to convert the 60 layers of the image data to RGB channels.

Maybe you want:

`[r,c,m]  = size(Pi);rgbImage = repmat(reshape(Pi / 255, [r, c, 1, m]), [1, 1, 3, 1]);`
