A brightness colorimeter having a measurement error caused by linearly polarized light, which is corrected, includes: a lens module to which light irradiated from one side is input; a polarization conversion module configured to penetrate the light input through the lens module to convert polarization characteristics; a spectral module provided in one unit block to reflect and penetrate the light input through the polarization conversion module so as to branch the light in different three directions; filter modules arranged on progress paths of the light branched in different three direction through the spectral module to penetrate monochromatic light beams having specific spectra among the light branched in the three directions; and measurement modules arranged to correspond to exit angles of the monochromatic light beams penetrated through the filter modules, to measure at least one of a brightness, a colorimeter and a defect obtained by the monochromatic light beams.

Systems, apparatuses, and methods for performing color channel correlation detection are disclosed. A compression engine performs a color channel transform on an original set of pixel data to generate a channel transformed set of pixel data. An analysis unit determines whether to compress the channel transformed set of pixel data or the original set of pixel data based on performing a comparison of the two sets of pixel data. In one scenario, the channel transformed set of pixel data is generated by calculating the difference between a first pixel component and a second pixel component for each pixel of the set of pixel data. The difference is then compared to the original first pixel component for each pixel. If the difference is less than or equal to the original for a threshold number of pixels, then the analysis unit decides to apply the color channel transform prior to compression.

A system for dispensing at least one makeup product, including a cup and a dispenser for filling the cup from the bottom with at least one product, the cup being secured to the dispenser at least while it is being filled with said product. The method for dispensing and evaluating makeup, including the steps of: allowing a video link to be established, for example over the Internet, from a camera at a first site to a second site, allowing the second site to operate either directly or indirectly a dispenser of such a dispensing system, present at the first site, this dispenser making it possible to vary the colour of mixture dispensed, and allowing a person present at the first site to apply the mixture dispensed and to send to the second site a corresponding image, so as to receive in return information relating to the result of the makeup.

Graphene quantum dots are functionalized by covalently bonding a corrosion inhibitor molecule thereto. In a useful method, a corrosion inhibitor compound is blended with a graphene quantum dot-tagged corrosion inhibitor compound, and the blend is applied to a metal surface, such as the interior of a carbon steel pipe. The blend inhibits corrosion arising from contact with produced water generated by hydrocarbon recovery from one or more subterranean reservoirs. The produced water having the blend dispersed therein is irradiated with a source of light having a selected first range of wavelengths, and the luminescent emission of the graphene quantum dot-tagged corrosion inhibitor is measured at a selected second range of wavelengths, thereby providing for real-time measurement of corrosion inhibitor concentration within the pipe.

A cradle can be used to capture video of an object, such as hair. That video can then be used to extract and visualize color information relating to that material using a colorcloud. The colorcloud contains all the colors that were present in one or more frames of the video. The cradle comprises a video recording device that is able to see the material through a window on the cradle. A smartphone can be used with the cradle to act as the video recording device, as well as provide lighting.

A printer includes: an inline scanner which acquires an RGB value of each patch of a color chart; an inline colorimeter which acquires a colorimetric value of each patch of the color chart; a profile creation unit which creates a profile for associating the RGB value with the colorimetric value of each patch; and a color conversion unit which estimates a colorimetric value corresponding to an RGB value of input data by extrapolation calculation using four points including three points forming a plane and one supporting point in data of the profile, wherein the color conversion unit estimates the colorimetric value corresponding to the RGB value based on a set of four points remained after deleting one or a plurality of sets of four points according to a predetermined rule from a plurality of sets of four points selected for an RGB value input.

Methods and systems for determining a radar compatible coating are provided. In one example, the method includes obtaining a reflectance measurement of a target coating to characterize a color of the target coating. One or more candidate formulas are generated to determine color matching to the color of the target coating. A corresponding color and a corresponding radar property for each of the one or more candidate formulations is predicted. A radar compatible coating composition that is the same or substantially similar in appearance to the target coating is generated. Generating the radar compatible coating composition is based at least in part on the corresponding color and the corresponding radar property for one of the one or more candidate formulations.
