Enhance Color Separation Using Decorrelation Stretching Decorrelation stretching enhances the color separation of an image with significant band-to-band correlation. The exaggerated colors improve visual interpretation and make feature discrimination easier. You apply decorrelation stretching with the decorrstretch function.

Decorrelation stretch image processing

𝗧𝗼𝗽𝗶𝗰: contrast stretching in digital image processing. 𝗦𝘂𝗯𝗷𝗲𝗰𝘁: Image Processing. 𝗧𝗼 𝗕𝗨𝗬 𝗻𝗼𝘁𝗲𝘀 𝗼𝗳 Decorrelation on RGB components of an input image. Learn more about image processing, c++, decorrelation stretch Image Processing Toolbox In image processing decorrelation techniques can be used to enhance or stretch, color differences found in each pixel of an image. Showing page 1.

The result of decorrelation stretch is generally an improvement in the range of intensities and saturation for each colour with the hue remaining unaltered. Decorrelation Stretch, like principal component analysis, can be based on the covariance matrix or the correlation matrix, the resultant value of the decorrelation stretch is also a function of the nature of the image to which it is applied.

Table 1. Contrast adjustment remaps image intensity values to the full display range of the data type. An image with good contrast has sharp differences between black and white.

method in [21] uses multi-view images of a highway sys-tem to detect trafﬁc anomalies, with each view monitoring a different road segment or intersection. The processing of the multiple views is non-distributed and the method does not model any correlations between views. Accurate anomaly detection requires decorrelation of the background

Another way to enhance the truecolor composite is to use a decorrelation stretch, which enhances color separation across highly correlated channels. Use decorrstretch to perform the decorrelation stretch. Specify the optional name-value pair 'Tol',0.1 to perform a linear contrast stretch after the decorrelation stretch. Again, surface features have become much more clearly visible, but in a different way.

It is a plugin to ImageJ.

In image processing decorrelation techniques can be used to enhance or stretch, color differences found in each pixel of an image. This is generally termed as 'decorrelation stretching'. The concept of decorrelation can be applied in many other fields.

Image method in [21] uses multi-view images of a highway sys-tem to detect trafﬁc anomalies, with each view monitoring a different road segment or intersection. The processing of the multiple views is non-distributed and the method does not model any correlations between views.
