Monitoring for maintenance or studies of energy efficiency in buildings, large infrastructure, industrial facilities, etc., are common nowadays. These kind developed with inspections which determine the state facilities that analysed. The difficulty is increased along size and complexity facility itself, even more when attribute to be surveyed not noticeable responsive human eye. In recent year...

In this letter, a method for path loss prediction in outdoor urban environments based on computer graphics technologies is presented. Each wall of buildings an evaluation area assigned to different RGB color. We create two types color images that are viewed from transmission point (Tx) and receiving points (Rxs). By analyzing comparing the colors these images, visible existed both corresponding...

The extended application of device-dependent systems’ vision is growing exponentially, but these systems face challenges in precisely imitating the human perception models established by device-independent Commission internationale de l’éclairage (CIE). We previously discussed theoretical treatment and experimental validation developing a calibrated integrated sphere imaging system to imitate v...

In this study, we evaluate the relationship between long-term variability of facial hue information in physiological and psychological regions interests (ROIs) health condition. Long-term information, RGB, L*a*b* color space, were obtained from 13 ROIs visible images measured for approximately six months. evaluation was performed based on four conditions (absolute value absolute L*a*b*, relativ...

Abstract An adaptive low-illumination image enhancement algorithm based on the weighted least squares optimization is proposed to solve difficulty of detailed feature recognition in images that collected by visible light imaging equipment. First, converted from RGB channel LAB channel. Second, we use an edge-preserving smoothing operator coarsen smooth base layer and extract multi-scale details...

In this paper, we propose a 3D color picker for virtual reality (VR) systems. Using the proposed picker, RGB and HSV spaces are displayed in shape, can be selected through one-step interaction by pointing at location inside space with device. This process is very simple compared multistep selection interactions required existing VR pickers. Since interior of not visible, also three types user i...

In order to improve contrast and restore color for underwater image captured by camera sensors without suffering from insufficient details and color cast, a fusion algorithm for image enhancement in different color spaces based on contrast limited adaptive histogram equalization (CLAHE) is proposed in this article. The original color image is first converted from RGB color space to two differen...

In this paper, we propose a novel interactive image segmentation method for RGB-D images using hierarchical Graph Cut. Considering the characteristics of RGB channels and depth channel in RGB-D image, we utilize Euclidean distance on RGB space and geodesic distance on 3D space to measure how likely a pixel belongs to foreground or background in color and depth respectively, and integrate the co...

Most of the existing approaches for RGB-D indoor scene labeling employ hand-crafted features for each modality independently and combine them in a heuristic manner. There has been some attempt on directly learning features from raw RGB-D data, but the performance is not satisfactory. In this paper, we adapt the unsupervised feature learning technique for RGB-D labeling as a multi-modality learn...

Mergers of globular clusters (GCs) once associated with dwarf spheroidal (dSph) galaxies have recently been suggested as an explanation for the bimodal horizontal branches (HBs) of some Galactic GCs, most notably NGC 1851, NGC 2808, and NGC 6229. Through analysis of the available color-magnitude diagrams for the GCs in the Fornax and Sagittarius dSph satellites of the Milky Way, as well as thei...
