Racial disparities in education have put a spotlight on the role of teachers and school environment that is created for students. As are seen as vital element climate, interactions between students can significant effect students’ success. The purpose this study was to examine associations race, skin tone, teacher–student relationship (TSR) quality. Data drawn from Fragile Families Child Wellbe...

This paper proposes a method for removing image inconsistencies which occur by an existence of moving objects or a change of illumination condition when an omnidirectional image database is generated. The database is used for archiving an outdoor scene in wide areas or generating novel view images with an image-based rendering approach. In related work, it is difficult to remove moving objects ...

Color device calibration is traditionally performed using one-dimensional per-channel tone-response corrections (TRCs). While one-dimensional TRCs are attractive in view of their low implementation complexity and efficient real-time processing of color images, their use severely restricts the degree of control that can be exercised along various device axes. A typical example is that 1-D TRCs i...

In this paper, we address the issue of color in high dynamic range (HDR) imaging. In contrast to state-of-the-art methods, we propose to move the complete HDR imaging process from RGB to a luminance-chrominance color space. Our aim is to get a more computationally efficient technique and to avoid also any possible color distortions originating from three color channels processed separately. To ...

-Steganography method used in this paper is based on biometrics. And the biometric feature used to implement steganography is skin tone region of images. Here secret data is embedded within skin region of image that will provide an excellent secure location for data hiding. For this skin tone detection is performed using HSV (Hue, Saturation and Value) color space. Additionally secret data embe...

Since 2015, it has been possible to modify certain emoji with a skin tone. The five different skin tones were introduced with the aim of representing more human diversity, but some commentators feared they might be used as a way to negatively represent other users/groups. This paper presents a quantitative analysis of the use of skin tone modifiers on emoji on Twitter, showing that users with d...

The mapping of the potentially high dynamic range of the real world luminance to the low dynamic range of photographic devices is one of the classic photographic tasks. Therefore, the colour rendering or colour reproduction method is proposed and described in many literatures over the past five decades. However, there are well-known problems associated with these methods. This paper presents a ...

High dynamic range imaging techniques involve capturing and storing real world radiance values that span many orders of magnitude. However, common display devices can usually reproduce intensity ranges only up to two to three orders of magnitude. Therefore, in order to display a high dynamic range image on a low dynamic range screen, the dynamic range of the image needs to be compressed without...

Grayscale images are fundamental to many image processing applications like data compression, feature extraction, printing and tone mapping. However, some information is lost when converting from color grayscale. In this paper, we propose a light-weight high-speed decolorization method based on human perception of temperatures. Chromatic aberration results differential refraction light dependin...
