Why don't you want to use imresize? What would be the point of writing another function that does exactly the same thing?

While using Imresize function I'm loosing the properties of my image........I want to enhance multiple images and display them with same size without giving manual size....

imresize includes numerous different algorithms for resizing an image and is likely to give you as good an answer as you can get in most cases, if you use an appropriate method with it.

What exactly are you doing with it? Making images bigger? smaller? How much bigger or smaller? image resizing can only interpolate data when making an image bigger. Some methods of interpolation are a lot better than others, but all of them essentially 'invent' data that is not really part of the original image.

Yes, any resizing has to involve some sort of interpolation ('nearest' is the most basic interpolation). What properties are you losing?

Note that you can display any image at any scale, without affecting the actual image pixels. Display is independent from storage.

imresize function needs manual width and height arguments....is there any option for displaying the images automatically with same size...

The same size as what? If you mean the same size as each other, then that involves deciding which size amongst the images is the one to resize to, and in that case you have a manual width and height anyway.

Oh Okay.. Now I understood...we should specify width and height for resizing an image... there is no automatic resize command and also resize command doesn't affect actual pixel of the image .......

Thank You for your support....
