This example shows how to perform a translation operation on an image using the
imtranslate function. A translation operation shifts an image by a specified number of pixels in either the x- or y-direction, or both.
Read an image into the workspace.
I = imread('cameraman.tif');
Display the image. The size of the image is 256-by-256 pixels. By default,
imshow displays the image with the upper right corner at (0,0).
figure imshow(I) title('Original Image')
Translate the image, shifting the image by 15 pixels in the x-direction and 25 pixels in the y-direction. Note that, by default,
imtranslate displays the translated image within the boundaries (or limits) of the original 256-by-256 image. This results in some of the translated image being clipped.
J = imtranslate(I,[15, 25]);
Display the translated image. The size of the image is 256-by-256 pixels.
figure imshow(J) title('Translated Image')
'OutputView' parameter set to
'full' to prevent clipping the translated image. The size of the new image is 281-by-271 pixels.
K = imtranslate(I,[15, 25],'OutputView','full');
Display the translated image.
