This paper describes a method to identify the extrinsic parameters of RGB-D cameras mounted on legged robots. Since the calculation of the parameters is based on the detection of the robots feet in the camera images, no special calibration objects are required. Therefore the method is simple to use and can even be applied automatically. Experiments demonstrate the precision and the robustness o...

Translucent materials are ubiquitous, and simulating their appearance requires accurate physical parameters. However, physicallyaccurate parameters for scattering materials are difficult to acquire. We introduce an optimization framework for measuring bulk scattering properties of homogeneous materials (phase function, scattering coefficient, and absorption coefficient) that is more accurate, a...

o m p p c B bstract. This paper proposes a driving current control method for back light unit (BLU), consisting of red, green, and blue (RGB) ight-emitting diodes (LEDs), whereby a RGB optical sensor is used o check the output color stimulus variation to enable a time-stable olor stimulus for light emission by the RGB LED BLU. First, to btain the present color stimulus information of the RGB LE...

We propose an angular map driven active contouring based on curve evolution using level sets to extract object from natural color images. The constraint parameters to stop the intrinsically evolving curve on the angular map of the color space (RGB used) are derived based upon a modified minimal partition problem.

This study developed sensory polymeric materials for the colorimetric sensing of TNT in aqueous media. Solid films and coated fabrics permitted the detection of TNT, through colour change, and its quantification, by taking a picture of the materials and processing their RGB parameters to define the evolved colour.

This paper introduce an equation to convert from RGB to RYB and the inverse conversion equation as a model of RYB color space. Proposal RYB color model allows paint like compositing easily without complex configuration of parameters such as Kubelka-Munk model. Keywords— RYB; Color; Compositing; Mixing

This paper gives a detailed study on the performance of oil paint image filter algorithm with various parameters applied on an image of RGB model. Oil Paint image processing, being very performance hungry, current research tries to find improvement using parallel pattern library. With increasing kernelsize, the processing time of oil paint image filter algorithm increases exponentially.

Bragg mirror designs for Optically Pumped Semiconductor Disk Lasers (OPSDLs) are presented. An optimization takes into account parameters such as reflectivity, thermal resistance, and strain. Calculations and first results are shown for devices with an emission wavelength of 920 nm. The wavelength is of particular interest since its second-harmonic yields 460 nm emission required for RGB displa...
