Spezielle Klassifizierungsregeln

This group focuses on image processing algorithms. Although such algorithms sometimes need to consider characteristics of the underlying image acquisition apparatus, inventions to the image acquisition apparatus per se are outside the scope of this group.

The classification symbol G06T 5/00 should be allocated to documents concerning:

Interactive / multiple choice image processing, e.g. choosing outputs from multiple enhancement algorithms;
Image restoration based on properties or models of the human vision system [HVS].
