Invariant representation in image processing
Arnold W. M. Smeulders, Jan‐Mark Geusebroek, Theo Gevers · 2002
The paper discusses the role of invariance in image processing, specifically the desire to discriminate against unwanted variations in the scene while maintaining the power to tell the difference between object-intrinsic characteristics and scene-accidental conditions. It provides an analysis and references of what are directly observables in a general scene.
