Indoor positioning systems based on visible light communication (VLC) using white light-emitting diodes (WLEDs) have been widely studied in the literature. In this paper, we present an indoor visible-light (VLP) system red–green–blue (RGB) LEDs and a frequency division multiplexing (FDM) scheme. This combines functions of FDM scheme at transmitters (RGB LEDs) received signal strength (RSS) tech...

Visual saliency detection is useful for applications like image segmentation, image retrieval et al. According to the thought that the near-infrared image can provide complementary information to the corresponding visible image, a new region based multispectral saliency detection method is proposed. The source images are decomposed into homogeneous regions by superpixel algorithm in 6-dimention...

In principle the Visible Human data sets are an ideal basis for building electronic atlases. While it is easy to construct such atlases by just ooering the possibility of browsing through the 2D slices, the construction of realistic 3D models is a huge project. As one rather easy way to establish three-dimensionality, we have registered the Visible Human data to the already existing 3D atlas VO...

Remote sensing of the structural and spectral traits of vegetation is being transformed by structure from motion (SFM) algorithms that combine overlapping images to produce three-dimensional (3D) red-green-blue (RGB) point clouds. However, much remains unknown about how these point clouds are used to observe vegetation, limiting the understanding of the results and future applications. Here, we...

The correct color of water and bottom refraction is one of the most important parts of realistic visual water simulation. The paper is devoted to the real time rendering of scenes with shallow water when the bottom is visible. It covers the model of light transport at the water surface and through the water medium that allows us to calculate spectral intensity of light at the surface; the human...

We investigate the advantages of a stereo, multi-spectral acquisition system for material classification in ground-level landscape images. Our novel system allows us to acquire high-resolution, multispectral stereo pairs using commodity photographic equipment. Given additional spectral information we obtain better classification of vegetation classes than the standard RGB case. We test the syst...

Computer interfaces for color selection consist of a visible screen representation, an input method, and the underlying conceptual organization of the color model. We report a two-way factorial, between-subject variable experiment which tested the effect of high and low visual feedback interfaces on speed and accuracy of color matching for RGB and HSV color models. The only significant effect w...
