In this paper, we propose an original approach in order to improve the results of color im-age segmentation by pixel classification. We define a new kind of color space by selecting a setof color components which can belong to any of the different classical color spaces. Suchspaces, which have neither psycho-visual nor physical color significance, are named hybridcolor space...

Color information of natural images can be considered as a highly correlated vector space. Many different color spaces have been proposed in the literature with different motivations toward modeling and analysis of this stochastic field. Recently, color transfer among different images has been under investigation. Color transferring consists of two major categories: colorizing grayscale images ...

The ability to restore perceived colors for the output of color imaging devices is of great interest. The quality of color reproduction depends on the accuracy of the color correction function used, on the recording and rendering illumination as well as on the spectral sensitivies of the color imaging device used. Much work has been done to develop and evaluate the quality of different color co...

(+)-γ-lactamase catalyzes the specific hydrolysis of (+)-γ-lactam out of the racemic γ-lactam (2-Azabicyclo[2.2.1]hept-5-en-3-one) to leave optically pure (-)-γ-lactam, which is the key building block of antiviral drugs such as carbovir and abacavir. However, no structural data has been reported on how the enzymes bind the γ-lactams and achieve their enantioselectivities. We previously identifi...

In this chapter, we propose a pixel adjustment procedure for digital watermarking methods using uniform color space. Many digital watermarking methods use uniform color space due to the convenience of controlling image quality (Yoshiura & Echizen, 2006). However, there is the problem that watermarked RGB integer pixel values in such methods are not quite corresponding to the watermarked real-nu...

This paper addresses the problem of automatically eliminating unwanted colour variation between similar image pairs. We propose a feature-based registration method to align colour histograms without any spatial processing of the image content or assumptions about the scene contents. We use the method for the colour transfer problem. The features are histogram maxima that persist through the sca...
