SolStretch 1.0.1

SolStretch is a lightweight and elegant Shiny app for applying decorrelation stretch to RGB raster images in TIFF or JPEG format. It enhances visual contrast by performing a PCA-based transformation, particularly useful for the analysis and digital enhancement of parietal art and prehistoric rock paintings.

Originally developed to support archaeological and paleolithic research, SolStretch enables rapid and user-friendly processing of imagery with optional brightness and contrast adjustments. The processed images can be downloaded in high-quality formats.
