How does the imreisze function works?
显示 更早的评论
Hello everyone. I was trying out the built-in hallway photo in MATLAB. I resized it by 1.5 times and 2 times than the original image. But somehow the 1.5 times version looks bigger to the naked eye? For low-res images, 1.5 times and 2 times resized images look their size though.
I was wondering if one could explain how the resize function is working here. Thanks!

If the image cannot fit fully on the screen, it will reduce the axes control until it will fit comfortably. Maybe the 1.5 just barely fit but the 2 would not and it resized the 2 to be smaller than the 1.5. You can always turn on the tick marks to see the actual pixel count:
axis('on', 'image');
Also, see attached zooming example.
