Abstract
A method and system for image scaling detection is provided. Image scaling detection involves receiving a decoded scaled input image having a plurality of pixels, wherein the input image has a scaling ratio relative to an original image; detecting blocking boundary artifact pixels in the image; determining a sum of pixel values for each blocking boundary artifact; detecting the pixel distance value between each pair or neighboring block boundaries; and determining the scaling ratio based on a distance value and said sum of pixel values.
