Original image?

This is just a sample image. You can use any colored image, e.g. colored Lena image.

Is this what you're looking for?

Similar but I am looking for black edges around the figure to show the respective scaling.

Pankaj, sorry, still the question is not clear to me.

Are you looking for reason of degradation (Image Restoration) or others?

Is it the down sampling image arbitarily to get the random scaling distortion?

What kind of distortion do you see in the attached image?

[pankaj singh]

I am looking for downscaled image. I have used

imresize(image)

function on the original figure. But it shows me the final figure in the whole figure window (as shown in your link). However, I need figure to be shown as above. Is it possible? In other words, I want to show the downsized image, but in the original image size figure window (the rest of the pixels may become zero).

Use padarray().
