摘要：A method and system for image scaling detection is provided. Image scalingdetection 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 eachblocking boundary artifact; detecting the pixel distance value between each pair orneighboring block boundaries; and determining the scaling ratio based on a distancevalue and said sum of pixel values.
