In order to acquire multispectral images precisely and quickly, a four-band multispectral capturing system with one imaging sensor is designed and evaluated in this paper. Firstly, four imaging bands are arranged in a 22 ...

patial filtering, which aims to mimic the contrast sensitivity function (CSF) of the human visual system (HVS), has previously been combined with color difference formulae for measuring color image reproduction errors. ...

Resolution in a projected display is traditionally defined by the number of pixels in the projector's spatial light modulator (SLM). In recent years, different techniques that increase the resolution on the screen above ...

Multi-dimensional look up tables (LUTs) are widely employed for color transformations due to its high accuracy and general applicability. Using the LUT model generally involves the color measurement of a large number of ...

I denne forprosjektstudien har arbeidsgruppen fra HiL og HiG vurdert hvilke metoder som kan benyttes til fargestyring (color management) i digital video. På bakgrunn av litteraturstudier, drøftinger og simuleringer har ...

Fluorescence is a photoluminescence phenomenon where light is absorbed at lower wavelengths and re-emitted at longer wavelengths. For classic artworks, fluorescence gives useful information about varnish and retouches. At ...

Hyperspectral imaging has become an increasingly used tool in the analysis of works of art. However, the quality of the acquired data and the processing of that data to produce accurate and reproducible spectral image cubes ...

Hyperspectral imaging has become a powerful technique for the non-invasive investigation of works of art. An advantage of this technique is the possibility to obtain spectral information over the entire spatial region of ...

Opacity is an important appearance attribute in the textile industry. Obscuring power and the way textile samples block light can define product quality and customer satisfaction in the lingerie, shirting, and curtain ...
