System design for accurately estimating the spectral reflectance of art paintings.

Improvement of the Classification of Hyperspectral images by Applying a Novel Method for Estimating Reference Reflectance Spectra

Hyperspectral image containing high spectral information has a large number of narrow spectral bands over a continuous spectral range. This allows the identification and recognition of materials and objects based on the comparison of the spectral reflectance of each of them in different wavelengths. Hence, hyperspectral image in the generation of land cover maps can be very efficient. In the hy...

Visible and infrared imaging spectroscopy of paintings and improved reflectography

Background: Imaging spectroscopy, the collection of spatially co-registered images in many contiguous spectral bands, has been developed for remote sensing of the Earth utilizing reflectance or luminescence. In this paper we summarize findings on the application of imaging spectroscopy to works of art in order to identify and map artists’ pigments, improve the visualization of preparatory sketc...

Multispectral Analysis and spectral Reflectance Reconstruction of Art Paintings

CIC@20: Multispectral Imaging

A variety of multi-spectral imaging methods are discussed for acquiring spectral information from a scene. We first review conventional multispectral imaging approach. The conventional imaging systems are mostly constructed by multi-band imaging devices with different filtration mechanism at the sensor side under passive illumination. We show some imaging devices, estimation algorithms, and app...

Estimation of surface properties for art paintings using a six- band scanner

The imaging systems using cameras to archive art paintings have several essential problems including image resolution and lens distortion. A scanner is considered as a precise imaging device, which can acquire images with high resolution and without camera lens distortion. The present paper proposes a method to estimate the surface properties of art paintings for digital archiving using the six...
