Discrete derivative approximations with scale-space properties: A basis for low-level feature extraction
This article shows how discrete derivative approximations can be defined so thatscale-space properties hold exactly also in the discrete domain. Starting from a set of natural requirements on the first processing...

Scale-space behaviour of local extrema and blobs
Elementary techniques from real analysis, and singularity theory are applied to derive analytical results for the behaviour in scale-space of critical points and related entities. The main results of the treat...

Analysis of aerosol images using the scale-space primal sketch
We outline a method to analyze aerosol images using the scale-space representation. The pictures, which are photographs of an aerosol generated by a fuel injector, contain phenomena that by a human observer ar...
