Compositional data from the New Horizons spacecraft's Ralph/Linear Etalon Imaging Spectral Array (LEISA) instrument, shown in the right inset, indicate that the plateau uplands south of Piri Rupes are rich in methane ice (shown in false color as purple).
Scientists analyzed these images in false color, a rendering method that makes it easier to distinguish differences among the types of particles suspended in the atmosphere-relatively small particles that make up haze-inside and outside the hexagon.
False color composites, band ratios, minimum noise fraction (MNF) analyses and supervised classification was performed on the visible near infrared (VNIR) and shortwave infrared (SWIR) bands.
Another standout is Michael Bill Smith's "Cardinal Tarcisio Bertone" (2011), featuring a false color image of the titular cardinal in infrared oranges and yellows on sparkling vinyl.
The device produces an interference pattern, a false color contour plot, and 2-D profile of the spherical test optic for analysis.
Some striking work has been done using computer-generated "false color" to present flow data (see, for instance, CIME, March 1984, p.
The acquisition is based on a wide-angle eye camera, which gives the eye a natural image (not a false color) and an autofluorescence image.
The photo, "False Color" comes from seafarer Mandy Buenconsejo.
Some lower-cost apo refractors I've used have sharp optics, but images are inevitably tinged with false color. With the 102-mm FCD I saw none--not a trace of false color even on demanding targets such as Vega, and on crater rims and the limb of the Moon.
With a built-in histogram, false color, focus peaking, waveform monitor and vectorscope, digging into the details of your video feeds has never been easier.
Band rationing technique was usedfor the study such as false color composite band ratio used for identifying lithological features ofthe study area.Laki Formation (limestone, Marl and Calcareous Shale rocks) is indicated by reddish yellow to pale yellow color; the Tiyon Formation (shale, Nodular Limestone and Limestone) is indicated by reddish brown to pale green color; the Nari Formation (Limestone, sandstones and shale) is indicated by light brownish green to dark green color; Khirtar Formation (shale, limestone and marl) is indicated by reddish brown to light green color, (Manchar Formation Sandstone and pebbly Conglomerate) is indicated by light blue and reddish brown, while the alluvial sediments and recent deposits) are indicated by light purple, pale green and reddish brown color.
