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. Decorrelation stretching is a way to enhance the color differences in an image.

The image is produced at pixel resolutions of 15 m for VNIR, 30 m 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 techniques can also be used for many other purposes, such as reducing crosstalk in a multi-channel signal, or in the design of echo cancellers. 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'.

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 decorrstretchfunction. 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. A decorrelation stretch is a linear, pixel-wise operation in which the specific parameters depend on the values of actual and desired (target) image statistics.

Recent and prospective decorrelation techniques for image processing Serge COMES * St6phane MAES * Marc VAN DROOGENBROECK ** Abstract This paper is devoted to the description of recent and prospective decorrelation techniques used in image pro- cessing. Two classes are taken into consideration : the 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.
