Decorrelation stretching enhances the color separation of an image with significant band-band correlation. The exaggerated colors improve visual interpretation and make feature discrimination easier. 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 If the data are transformed into principal components space and are stretched within this space, then the three bands making up the RGB colour composite images are subjected to stretch will be at the right angles to each other. To this end, we have applied the decorrelation stretch to processing of spectral images.

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. 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. Adaptive histogram equalization adjusts image intensity in small regions in the image.

It needs to be installed first before you can use DStretch. Make a contribution and email DStretch@prodigy.net to get DStretch. decorrstretch.

Decorrelation Stretch is an image enhancement technique widely used in remote sensing to improve image quality of multi-spectral satellite imagery.

Thus it is useful for feature extraction.

DStretch supports several different colorspaces (see below). The image is converted from RGB to the colorspace, the calculation and transformation is performed, and then the colors are converted back to RGB before writing into a digital image. Use Decorrelation Stretch to remove the high correlation commonly found in multispectral data sets and to produce a more colorful color composite image. The highly correlated data sets often produce quite bland color images. Decorrelation stretching requires three bands for input.

To this end, we have applied the decorrelation stretch to processing of spectral images. We have found the following.
