image processing-zooming an image using Bilinear interpolation

Bi linear interpolation method has been used here for zooming images by a positive integer factor.

An image in your root directory can be zoomed by calling the above program.

*First try with a small image. Because when the image is smaller, program response quickly.

How to Run the Program

*copy bilinear_zoom.m file and the image file to your work directory.

Example-
*if the name of image in root directory is image.jpg and the zooming factor you expect is 5.

*run following code in command window.
bilinear_zoom('image.jpg',5);

*Use the enter key always, when the display does not show any change.
