[1] Using a combination of idealized radiative transfer simulations and a case study from the first field campaign of the Saharan Mineral Dust Experiment (SAMUM) in southern Morocco, this paper provides a systematic assessment of the limitations of the widely used Spinning Enhanced Visible and Infrared Imager (SEVIRI) red-green-blue (RGB) thermal infrared dust product. Both analyses indicate th...

This paper considers the improved method for segmenting complex structured images acquired from space observation systems based on particle swarm algorithm. Unlike known ones, algorithm involves following: – highlighting brightness channels in Red-Green-Blue color space; using a image each channel of RGB segmentation is reduced to calculating objective function, moving speed, and new location c...

A pixel-level fusion technique for RGB representation of multispectral images is proposed. The technique results in highly correlated RGB components, a fact which occurs in natural colour images and is strictly related to the colour perception attributes of the human eye. Accordingly, specific properties for the covariance matrix of the final RGB image are demanded. Mutual information is employ...

In this paper, an effective image demosaicking algorithm, which is based on the correlation among the three primary colors, is proposed for mosaic image with Bayer color filter array (CFA). To reduce the distortion and improve the reconstruction quality, the proposed interpolation method makes full use of the brightness information and the edge information. We design several filters with size o...

The red-blue-green (RGB) calibration technique consists in constructing an a priori calibration table of the isochromatic retardation versus the triplet of RGB values obtained with a RGB CCD camera. In this way a lookup table (LUT) is built in which the entry is the corresponding RGB triplet and the output is the given retardation. This calibration (a radiometric quantity) depends on the geomet...

Leaf color is a good indicator of plant’s health status. In this study, new image acquisition technique was developed to estimate chlorophyll content lettuce leaves. The images leaves grown under artificial light were acquired using smartphone. Leaves captured by directly attached the camera lens with aid background illumination from SMD LED. Red, green, blue (RGB) indices extracted and some ve...

Remote sensing images are acquired using special platforms, sensors and classified as aerial, multispectral hyperspectral images. Multispectral represented large spectral vectors compared to normal Red, Green, Blue (RGB) Hence, remote image retrieval process from archives is a challenging task. mainly consist of feature representation first step finding out similar query second step. Feature pl...

Various Steganography algorithms have been proposed and implemented for hiding the existence of data in a cover object starting from the algorithms that work in transform domain to the ones that work in spatial domain, such as Least Significant Bit (LSB), which uses the three colours (RED, GREEN and BLUE) present in an image. Three colours are present in the pixel of an image, therefore, this p...

Conventional digital cameras, the Nikon Coolpix885(®) and the SeaLife ECOshot(®), were used as in situ optical instruments for water quality monitoring. Measured response spectra showed that these digital cameras are basically three-band radiometers. The response values in the red, green and blue bands, quantified by RGB values of digital images of the water surface, were comparable to measurem...

2 I. INTRODUCTION We have been practicing spectral color estimation for museum artwork imaging and spectral estimation. We have had success using both narrow-band imaging based on a liquid crystal tunable filter (LCTF) and various broad-band imaging approaches using the same monochromatic digital camera system. Details about our spectral color imaging system description, imaging procedures and ...
