Painting on a wall of Angkor Wat of a Boat via DStretch using LRE Colourspace for Colour Decorrelation Stretching

From The hidden paintings of Angkor Wat, "Boats are a common subject for painting on the walls of Angkor Wat. Boat paintings have already been noted on the outer wall where they are clearly visible; similar boat paintings on the walls of the second enclosure are also generally visible, although a few were only detected after digital enhancement. It is possible that the boat paintings in separate parts of the temple are related. The boats portrayed display a wide variety of designs, from small-to-medium sized canoes with curved hulls to large, flat-bottomed barges. Oars and rudders are often depicted, and many depictions show boats with multiple oars which would indicate that some were fairly sizeable. The most notable depictions of boats at Angkor are on the bas-reliefs of the Bayon, but research on boat types is still ongoing (Walker-Vadillo 2011). The boats are painted only in red."
