چکیده

The contribution deals with the Matlab application used for television colorimetry and color spaces analysis. The mathematical description of known color spaces (RGB, XYZ, YUV, YIQ, YCbCr, HSV, CMY, CMYK) is introduced including their reciprocal transformation. The application allows selection of input color image, direct and backward transformation into the selected space including MKO, CIE and RG diagram picture analysis. The projection of color image in 2D and 3D color vectors is then possible. The additional functions are evaluation of histogram, gamma correction, picture line selection for the analysis etc. The Color_Spaces application outputs are introduced in examples applied on various test pictures.

The Influence of pH, Temperature and Time on Dyeing of Silk Fabric by Black Bean Anthocyanin-rich Extract as Colorant

Anthocyanins are natural dye substances that provide attractive colors from red to blue. However, large quantities of Anthocyanins have been found in wastewater from soaked black beans, resulting in environmental pollution. The utilization of theses wastewaters would therefore be an effective way of reducing environmental pollution, and the water could be used to dye silk fabric, displaying...

Instrument dependency of Kubelka-Munk theory in computer color matching

Different industries are usually faced with computer color matching as an important problem. The most famous formula which is commonly used for recipe prediction is based on Kubelka-Munk K-M theory. Considering that spectrophotometer’s geometry and its situation influence the measured spectral values, the performance of this method can be affected by the instrument. In the present study, three ...

CIE Colorimetry and Colour Displays

CIE colorimetry was standardised 65 years ago to describe colorimetric properties of signal lights. The first real application of CIE colorimetry occurred, however, in the textile and coating industries to describe colour matches between sample and reference. Thus also the experiments conducted to achieve a uniform colour scale diagram were performed by using material samples usually illuminate...

Color and Weave Relationship in Woven Fabrics

In woven designs from colored threads, a colored pattern is a consequence of two possible arrangements where warp is over the weft or vice versa. Thus the primary elements of woven fabric design are combination of weaves and blending of colors using such weaves. Weave is the scheme or plan of interlacing the warp and weft yarns that produce the integrated fabric. Weave relates specially to the ...

Modelling and Performance Evaluation of Physical Layer of Wireless Regional Area Networks (IEEE 802.22) over AWGN Channel

The IEEE 802.22 stands for Wireless Regional Area Network (WRAN). WRAN uses the white spaces & unused VHF & UHF TV Bands. Cognitive Radio (CR) is a key to develop such a wireless standard. It is based on Time division multiplexing and Orthogonal Frequency Division Multiple Access. WRAN is developed for rural areas where utilization can be very low. In this paper we provide a detail overview of ...
