Multispectral Imaging in Multimedia
نویسنده
چکیده
An application of multispectral imaging in multimedia is presented. We describe a system for the acquisition of multispectral images using a CCD camera with carefully selected optical filters. We further discuss how the surface spectral reflectance of the imaged objects may be reconstructed from the camera response. We then present an application where the acquired multispectral images are used to predict changes in colour due to changes in the viewing illuminant. This method of illuminant simulation is found to be very accurate, and working on a wide range of illuminants having very different spectral properties.

متن کاملSpectral Estimation of Printed Colors Using a Scanner, Conventional Color Filters and applying backpropagation Neural Network
Reconstruction the spectral data of color samples using conventional color devices such as a digital camera or scanner is always of interest. Nowadays, multispectral imaging has introduced a feasible method to estimate the spectral reflectance of the images utilizing more than three-channel imaging. The goal of this study is to spectrally characterize a color scanner using a set of conventional...

متن کاملMultispectral imaging and image processing
The color accuracy of conventional RGB cameras is not sufficient for many color-critical applications. One of these applications, namely the measurement of color defects in yarns, is why Prof. Til Aach and the Institute of Image Processing and Computer Vision (RWTH Aachen University, Germany) started off with multispectral imaging. The first acquisition device was a camera using a monochrome se...
