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.
*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.
*Use the enter key always, when the display does not show any change.
*If you want to know the the algorithm used refer-:
I tested your version with Matlab's. However, this is the result:
PSNR (interpolatedImage: bilinear) = +29.00789 dB
PSNR (interpolatedImage: bilinear) = +35.77969 dB
Error rate: 23.34466 %
Good work Dimuthu!
