False Coloring is implemented using two different methods: colour enhancement and colour transformation. Colour enhancement refers to the process of using the grayscale value of each pixel tolook up its corresponding false colour. In this method, we have a pre-defined false colour set (the falseColorArray in FalseColoring.kt) which is a mapping between pixels of certain grayscale valueto the corresponding false colour. On the other hand, colour transformation refers to the idea of alteringthe RGB channels to form false colour. This method works by recalculating the RGB values of a pixel shown below.
