Reference-based color texture digitization and analysis of wooden surfaces

In this article we present our controlled environment and approach for reference-based color texture digitization and color texture analysis in the context of color wooden textured surface analysis for the final goal of a valid, controlled and reproducible varnishing process. The color digitization process is performed using a color checker and controlled illumination, followed by a color correction step based on the assumption of a linear transformation. The color image acquisition protocol includes also multispectral data acquisition using a spectrophotometer. We demonstrate the usage of our approach both on raw and varnished wooden samples. Further on, we compute several color and color texture features for the analysis of the acquired color texture images. We present and discuss our results and conclude this paper.
