Browser image resize algorithm discrepancies.

In this experiment, a 24x24 block is cropped from a scan representing more or less a white surface. The resulting image is a pattern made from scanner noise.
The resulting image is put into an HTML table (as below) and resized at chosen sizes to test how well the browser resolves the warped image.
With a good resizing & interpolation/anti-aliasing algorithm, the resized image should not differ too much from the original.
I have set the background to the original to provide a easy comparison between the original and resized images.
