Overall, the Decorrelation Stretch product appears to be performing as expected, and producing satisfactory products. For scenes of normal variability, correlation coefficients are typically less than 0.01 in absolute value (0.0 is the ideal case), and channel means are within 0.3 DN (0.2 percent) of target value.

Note You can apply a linear contrast stretch as a separate operation after performing a decorrelation stretch, using stretchlim and imadjust.This alternative, however, often gives inferior results for uint8 and uint16 images, because the pixel values must be clamped to [0 255] (or [0 65535]).The Tol option in decorrstretch circumvents this limitation. 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. IHS_Decorrelation_Stretch_v16_6_1.gmdx: In the provided model the user specifies which three bands represent data that is usually displayed as an RGB color composite. For true color aerial photography this would normally be 1,2,3, but may vary for other sensors. Decorrelation Stretch AST06 The decorrelation stretch is a process that is used to enhance (stretch) the color differences found in a color image.

A direct decorrelation stretch of a RGB colour image is achieved by decreasing the magnitude of the achromatic component of the colour vector for the pixel being processed. 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. The decorrelation stretch analysis produces a 3x3 numeric matrix as an end result that specifies the color transformation to be performed.

6.2. A power transfer function of a receiver is given by Q = α log β P where Q is the output and P the input and α, β are constants.
