Linear Scale-Space II: Early Visual Operations

In the previous chapter a formal justification has been given for using linear filtering as an initial step in early processing of image data (see also section 5 in this chapter). More importantly, a catalogue has been provided of what filter kernels are natural to use, as well as an extensive theoretical explanation of how different kernels of different orders and at different scales can be related. This forms the basis of a theoretically well-founded modeling of visual front-end operators with a smoothing effect.
