How to rescale the image?

I have set of true color images(about 700 images) and the image size: 1482 rows and 1506 columns. What i would like to do :

1) Rescale those images (currently i have pixel values but i need to get them either in cm/mm)

2) Find the minimum size for all the images and rescale all the images to that size. How to get along with this? Any suggestions?

Thanks in advance.

help "whos" - size bites help "imresize" - resize a image help "sizes" - dimension of a matriz

God work!

Well i think i have missed out some part in my question- really sorry about that.

imresize doesn't help much(atleast in the beginning) of this task. Reason is that i have an image and that image has a physical ruler placed on it. So what i want here is to find the x axis and y axis distance. Again, i want the distance in cm/mm not in pixel. Since there are lot of images i would like to run it for the whole batch and scale down all the images to the minimum x and y values. Any link/website that i can refer to?

See my attached spatial calibration demo. Once you know the size or location that you want to extract from the image, you can call imresize() and imcrop() to do that.

Image Analyst- thank you so much for your response. Moreover,your spatial calibration demo is just perfect. Thanks a million !!!
