Authomatic method based on image analysis for pilling evaluation in fabrics
Contiene fórmulas, gráficos y fotografíasA fully automatic method for pilling evaluation in wear-andtear
fabrics is developed from the image analysis of a set of standard
photographs (Zweigle KG-741 Reutlingen). The method involves operations
in both the spatial and frequency domains to segment pills from the
textured background of the web. It calculates the total area of pilling in
the sample image and assigns a degree of pilling according to the standard.
Two mathematical descriptions are analyzed according to the underlying
rule established by the standard images, using the visual estimation
of the area of pilling performed by a group of observers. A
logarithmic (in base two) approach, which is consistent with human visual
perception laws and facilitates an optimization of the method, is
eventually adopted.We acknowledge the Comisión Interministerial de Ciencia
