av L Bryngemark · Citerat av 4 — description of the analysis method details and the results from the dijet measurements is stretched [22]. If two quarks geometrical image of how likely it is to Using both observables, they can be decorrelated to isolate the impact of in-time.
It also uses decorrelation stretch as part of its workflow. Three images (visible, near-ultraviolet and near-infrared) were processed in TMSB using "Photography
Initially, the R, G, and B digital numbers (DNs) for each colour pixel are examined and the lowest value (it could be the red, green or blue) is selected. In other terms, images often contains simpler "objects" (in terms of morphology: bumps, edges, textures) that are mixed, or distorted. Generally, unmixing them via decorrelation somehow simplify further processing. Generally yes, unless you have uncorrelated noise in your images.

The primary purpose of decorrelation stretch is visual enhancement. Small adjustments to TOL can strongly affect the visual appearance of the output.

DStretch is a tool for rock art researchers who wish to enhance images of pictographs. It is a plugin to ImageJ. ImageJ is an image processing and analysis program written in Java. It needs to be installed first before you can use DStretch. Make a contribution and email DStretch@prodigy.net to get DStretch.
Presently, remote sensing datasets available from various earth orbiting satellites are being used extensively in various domains including in civil engineering, water resources, earth sciences, transportation engineering, navigation etc. Google Earth has further Decorrelation stretch, an image enhancement technique first used in remote sensing, can be usefully applied to rock art. In pictograph images from Baja California, California, and Nevada I demonstrate its ability to bring out elements nearly invisible to the eye and to improve visualization of difficult sites. A decorrelation stretch plugin to the imaging program ImageJ is available from the The decorrelation stretch is a process to enhance (in image processing parlance, “stretch”) the color differences found in a color image by a method that includes the removal of the inter-channel correlation found in the input pixels; hence, the term “decorrelation stretch”. The image is produced at pixel resolutions of 15 m for VNIR, 30 m Decorrelation Stretching. Decorrelation stretching enhances the color separation of an image with significant band-band correlation.

See Linear Contrast Stretching on how to add an optional linear contrast stretch to the decorrelation stretch. The number of color bands, NBANDS, in the image is usually three. But you can apply decorrelation stretching regardless of the number of color bands. The primary purpose of decorrelation stretch is visual enhancement.
