Standardization of a Color Cube Test

Detecting buried channels using linear least square RGB color stacking method based on deconvolutive short time Fourier transform

Buried channels are one of the stratigraphic hydrocarbon traps. They are often filled with a variety of porous and permeable sediments so they are important in the exploration of oil and gas reservoirs. In reflection seismic data, high-frequency components are sensitive to the channel thickness, whereas, low-frequency components are sensitive to the channel infill materials. Therefore, decompos...

The Application of the Hutt Color Cube Test to a Group of Subnormal Mentality

Human observers compensate for secondary illumination originating in nearby chromatic surfaces.

In complex scenes, the light absorbed and re-emitted by one surface can serve as a source of illumination for a second. We examine whether observers systematically discount this secondary illumination when estimating surface color. We asked six naïve observers to make achromatic settings of a small test patch adjacent to a brightly colored orange cube in rendered scenes. The orientation of the ...

Image Color Cube Dimensional Filtering and Visualization

W e cal l RGB cube the three dimensional representation of the colors of a digital image in RGB space. This cube simply shows the (R,G,B) color points which actually appear in the digital image. This visualization has, however, two main defects: it does not show the real RGB histogram. The difference is that in the color cube each point is plotted with its own color, while in the RGB histogram ...

Placing Arbitrary Objects in a Real Scene Using a Color Cube for Pose Estimation

We describe an Augmented Reality system using the corners of a color cube for camera calibration. In the augmented image the cube is replaced by a computer generated virtual object. The cube is localized in an image by the CSC color segmentation algorithm. The camera projection matrix is estimated with a linear method that is followed by a nonlinear refinement step. Because of possible missclas...
