The present paper focuses on non-linear pattern matching based on the Logarithmic Image Processing (LIP) Model. Our contribution consists first of using the scalar multiplication defined in the LIP context to extend the little-known Asplünd׳s metric to gray level images. Such a metric is explainable as a novel technique of double-sided image probing and presents the decisive advantage of being physically...
The production of polished metal surfaces addresses a large number of fields such as medical prostheses, jewellery or moulds. These surfaces are checked by people who rarely agree on the definition of the right geometry limit of scratches. The aim of this work is to study human vision of scratches. The first step was to produce calibrated scratches barely visible by the human eye on polished metal...
This paper proposes a new descriptor for textures, obtained by an independent components analysis (ICA) applied to image wavelet subbands. In certain conditions, ICA refines the wavelet multiband analysis. The descriptor, consisting in the independent components (ICs) distribution parameters, serves as basis for the textile image signature in a recognition application. By using the Kullback-Liebler...
