MATLAB: How to show a interpolated Image with its actual color

Question

Hi,

I am working with image interpolation. My Input image is a RGB image. The resultant image after interpolation seems to be gray-scale. How to show the resultant interpolated image in color ?

Please help me. Thanks in advance.

Code

X = imread('home.jpg');
V = single(X(1:124,75:225));
figure
imshow(uint8(V));
title('Original Image');
imwrite(uint8(V),'1_InputImage.jpg');
Vq = interp2(V,1);
figure
imshow(uint8(Vq));
title('Linear Interpolation');
imwrite(uint8(Vq),'2_LinearInterpolated.jpg');

Input Image

Answer 1

interp2() works with 2D matrices, not 3D color images. Use imresize() instead.
