This implementation is too basic. And 8x8 DCT blocks, should effectively prevent block detection :/

I searched about interesting papers. There are some, but you'll find they don't give much informations on how to implement these algorithms.

An interesting video quality metric is PDM ( Perceptual Distorsion Metric), that looks really good on paper. From Stefan Winkler. He has many papers on the web.

You could search for Watson too, he created the VQM metric.

There was some results from VQEG, PSNR was still quite good, but PDM was easily above.
