Spatial resolution is a key parameter in many applications of image processing. In order to improve the spatial resolution we make use of super resolution algorithms. In this paper an SR image reconstruction algorithm is proposed using Integer wavelet transform (IWT) and Bit plane technique (BTP). The proposed method is analyzed in different color space transforms such as RGB, Ycbcr and CIELAB ...

The ultimate goal of realistic image synthesis is to generate computer imagery that is perceptually indistinguishable from its real-world counterpart. Many rendering techniques have been proposed, making tremendous progress to reach this goal. Now we are faced with two basic questions. How far we are from the goal? How well the existing techniques perform? No doubt a quantitative definition or ...

Most studies of surface color appearance have ignored 3-D illumination phenomena such as shadows and interreflections. These phenomena must affect surface color appearance to some extent, but without a model we cannot make claims about how great these effects really are. In this article, we introduce a simple model of how interreflections can affect color appearance. We consider a family of ide...

This paper proposes a method for designing a color lookup table (CLUT) that can simultaneously process gamut mapping and color space conversion without any complex computation. After constructing a LUT composed of the scanner and printer gamuts, fictive sample points are uniformly selected in CIELAB space and CMY values computed using gamut mapping. The scanner input RGB image is then converted...

This work uses the S-CIELAB color model to compare images that have been calibrated and processed using a colorimetric dithering method which simulates increments in viewing distance. Firstly, we obtain XYZ calibrated images by applying the appropriate color transformations to the original images. These transformations depend on whether the image is viewed on a display device or encoded by a ca...

A measure is developed for comparing complex scenes produced by single-chip digital color cameras. The proposed measure is based on the CIELAB color space with appropriate considerations to the sensitivity of the Human Visual System (HVS) when viewing a complex scene. For comparison purposes, the error measures proposed have been implemented using the , and the recently recommended color differ...

The meat industry in recent years leaning towards the replacement of synthetic antioxidants, such as BHT, for natural, mostly plant-based alternatives. For purpose, polyphenol-rich plant species are selected and researched. Amelanchier (Amelanchier alnifolia) fruit seems to be an interesting option adding products increase oxidative stability. In our study, we incorporate 3 5 ml extract into po...

Abstract Fricke gel dosimeters were prepared using a matrix based on poly(vinyl-alcohol) chemical cross-linked with glutaraldehyde and loaded Xylenol Orange. The samples irradiated gamma rays to doses in the range of 5–30 Gy consequent color changes investigated by spectrophotometric colorimetric techniques. Starting from measurement transmittance spectra, an analysis was carried out considerin...

A vehicle license plate recognition system extracts plate information from a digital image through image processing technology. License plate extraction (LPE) is the premise and key concept of license plate recognition systems. In China, two-row license plates are yellow and dirty. Thus, a novel license plate extraction method based on CIELab color space is proposed in this paper. The method in...

This paper describes a method for constructing a lookup table relating a three-dimensional CMY coordinate system to CMYK colorant amounts in a way that maximizes the utilization of the printer gamut volume. The method is based on an assumption, satisfied by most printers, that adding a black colorant to any combination of CMY colorants does not result in a color with more chroma. Therefore the ...
