| Hello Wolfgang
| I believe that you may be able to do this as follows:
| 
| 1. To get the 8x8 downsized block average of the pixel values in an 
| image do the following:
| 
| convert image.jpg -filter box -resize 128x96 average.jpg
| 
If the image size is not known (but is a multiple of 8) you can use...

    convert image.jpg -filter box -resize 12.5% average.jpg
