We present 3DMV, a novel method for 3D semantic scene segmentation of RGB-D scans in indoor environments using a joint 3Dmulti-view prediction network. In contrast to existing methods that either use geometry or RGB data as input for this task, we combine both data modalities in a joint, end-to-end network architecture. Rather than simply projecting color data into a volumetric grid and operati...

Better understanding of plant root dynamics is essential to improve resource use efficiency of agricultural systems and increase the resistance of crop cultivars against environmental stresses. An experimental protocol is presented for RGB and hyperspectral imaging of root systems. The approach uses rhizoboxes where plants grow in natural soil over a longer time to observe fully developed root ...

The first step in performing colour-based segmentation is choosing an appropriate colour space in which to operate from the wide variety of choices such as RGB, HSV, CMYK, YCbCr, etc [1]. Of these, RGB (red-greenblue) and HSV (hue-saturation-value) have been the most widely used. Figure 1 illustrates the geometries of the two spaces. By way of example, HSV representation has certain advantages ...

Tunable leaky-mode resonant silicon-nitride pixels providing red/green/blue spectral lines are analyzed. Critical dimensions, rate of tuning, linewidths, and polarization properties are quantified. ©2007 Optical Society of America OCIS codes: (050.1950) Diffraction gratings; (310.2790) guided waves; (120.2440) filters. Microelectromechanical systems (MEMS) methods are useful for tuning the spec...

The magnitude of nonconstant luminance errors This note outlines the magnitude of the errors introduced by the failure of contemporary video systems to adhere to the Principle of constant luminance. I assume that you are familiar with chapters 5 through 9 of my book, and that you are aware of the ambiguity and confusion in television engineering concerning the term luminance. I express signal p...

Human activity recognition based on RGB-D data has received more attention in recent years. We propose a spatiotemporal feature named three-dimensional (3D) sparse motion scale-invariant feature transform (SIFT) from RGB-D data for activity recognition. First, we build pyramids as scale space for each RGB and depth frame, and then use Shi-Tomasi corner detector and sparse optical flow to quickl...

In this cryptosystem, we have considered RGB images for two-dimensional (2D) data security. Security of RGB images during transmission is a major concern, discussed globally. This paper proposes a novel technique for color image security by random hill cipher (RHC) over SLn(F) domain associated with 2D discrete wavelet transform. Existing techniques have discussed the security of image data on ...

Despite significant progress, image saliency detection still remains a challenging task in complex scenes and environments. Integrating multiple different but complementary cues, like RGB and Thermal (RGB-T), may be an effective way for boosting saliency detection performance. The current research in this direction, however, is limited by the lack of a comprehensive benchmark. This work contrib...

Many spectral-recovery methods using RGB digital cameras assume the underlying smoothness of illuminant and reflectance spectra, and apply low-dimensional linear models. The aim of the present work was to test whether a direct-mapping method could be used instead of a linear-models approach to recover spectral radiances and reflectances from natural scenes with an RGB digital camera and colored...
