1 In this study, a digital CMOS camera was calibrated for use as a non-contact 2 colorimeter for measuring the color of granite artworks. The low chroma values of the 3 granite, which yield similar stimulation of the three color channels of the camera, 4 proved to be the most challenging aspect of the task. The appropriate parameters for 5 converting the device-dependent RGB color space into a ...
Morphological Color-Change in the Red-Backed Salamander (Plethodon cinereus) While Kept in Captivity
Coloration is a trait frequently cited as important to ecological, and thus evolutionary, processes in amphibians. To fully understand the impact of coloration, a consistent method of color measurement is required, which is often achieved by collecting color information in a captive, laboratory setting. However, results from the lab can only be generalized to the field if coloration remains con...
This paper describes a method for recognizing partially occluded objects to realize a bin-picking task under different levels of illumination brightness by using the eigen-space analysis. In the proposed method, a measured color in the RGB color space is transformed into the HSV color space. Then, the hue of the measured color, which is invariant to change in illumination brightness and directi...
We propose the integration of color and texture cues as an improvement of a rough set–based segmentation approach, previously implemented using only color features. Whereas other methods ignore the information of neighboring pixels, the rough set–based approximations associate pixels locally. Additionally, our method takes into account pixel similarity in both color and texture features. Moreov...
Colorizing grayscale video is a useful technique in scientific computing visualization and entertainment. In this paper, we introduce a method to transfer color from a reference image to the whole video. Although the general problem of adding chromatic values to a grayscale image has no exact, objective solution, the current approach attempts to free user from laborious work, except that the us...
This work describes an implementation for skin detection which relies on the H channel to characterize the skin colors range. The openCv library is used for image processing. The program initially converts RGB images to HSV one. The H channel is used to characterize the colors range for skin detection. To illustrate the approach we compare this with others.
In this paper, we describe a new approach for color image segmentation which is considered as a problem of pixels classification. The algorithm is applied to classify pixels of soccer color images in order to recognize the team of players. The color pixels classification algorithm is achieved in a new color space, the Hybrid Color Space, which is determined thanks to a supervised learning schem...
This paper addresses Paul Churchland’s (2007) attempt to identify colors with surface reflectance spectra. Of particular concern is Churchland’s novel method of approximating surface reflectance spectra. While those approximations are generated by objective means and yield a striking match with human phenomenological color space, they are not physically meaningful. The reason for this is that t...
The current paper proposes a novel color correction approach based on a probabilistic segmentation framework by using 3D Gaussian Mixture Models. Regions are used to compute local color correction functions, which are then combined to obtain the final corrected image. The proposed approach is evaluated using both a recently published metric and two large data sets composed of seventy images. Th...
