Abstract. The three-stage decorrelation stretch analysis—transformation to principal component scores; contrast-stretching of the scores to equalise the variances; and reversal of the initial transformation—is shown to produce linear combinations of the original bands which are uncorrelated and have unit variances.

The exaggerated colors improve visual interpretation  Users of ASTER data have found Decorrelation Stretching to be particularly effective in image display. The stretch is effective whether the bands used are in the  image data fusion. decorrelation stretch. PCA transformation. ancient history.

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.

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. 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 and reading from right to left, you can see that the decorrelation stretch: Removes a mean from each band Normalizes each band by its standard deviation (correlation-based method only) Rotates the bands into the eigenspace of Corr or Cov Applies a stretch S in the eigenspace, leaving the image Decorrelation Stretch AST06 The decorrelation stretch is a process that is used to enhance (stretch) the color differences found in a color image.

av M Blomqvist · 2010 — How much the universe has been stretched between a time t and the current but can be decorrelated by rotating them into a basis where they are diagonal.

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 … and reading from right to left, you can see that the decorrelation stretch: Removes a mean from each band Normalizes each band by its standard deviation (correlation-based method only) Rotates the bands into the eigenspace of Corr or Cov Applies a stretch S in the eigenspace, leaving the image Decorrelation stretch in Python.
