Resize image ,but xy axis not start with 0.

4 views (last 30 days)
I'm trying to resize the image. Now I using this code to resize
img = imread('color3.jpg');
img2=rgb2gray(img)
resizedimage = imresize(img2,[40 60]);
From this I got image, x-axis from 0 to 60 and y-axis 0 to 40.
But I want x-axis from 30 to 60 and y-axis 10 to 40.
How can I do that?

Not sure what you're talking about. The first row or column of a matrix is 1, not 0. Why/where are you seeing zero?
This works and you can see from the tick marks and counting over from column 10 to the first column that the first column is 1.
img = imread('peppers.png');
img2=rgb2gray(img);
resizedimage = imresize(img2,[40 60]);
imshow(resizedimage, 'InitialMagnification', 1000);
axis('on', 'image');

What does that mean? img is already in the workspace. To save the image to disk you can use imwrite(). To save the axes or figure (with title, tick labels, etc.) use saveas() or exportgraphics (R2020b or later).

No, it's not working. Also I want to resize, but this command cut some parts out.
