Development of an image-based measurement instrument for gloss characterization

Abstract Gloss is one of the main attributes to describe appearance surfaces and objects, as it contributes general quality perception. a multidimensional quantity which ‘specular gloss’ most commonly applied attribute. Specular gloss meters are standardized widely used in industry. However, their readings correlate only partially visual impression, also comprises distinctness-of-the-reflected-image (DOI), haze, contrast surface-uniformity attributes. This study presents more profound image-based meter (iGM) incorporates CMOS camera detector. concept not new, but limited research has been conducted on inclusion various image processing evaluations for The designed iGM compatible 60° specular standards. detector captures reflected source image, processed measure four perceptual surface gloss. obtained results validate evaluation indicate promising capability characterizing DOI, contrast. Contrast an important attribute that available yet industrial meters. It measured using diffuse aspecular light source. Generally, this maintains hardware principles meters, while evolving toward representative perception meter.
