Research on climate change based on carbonate porosity analysis in Jinping, China

shows the process of obtaining the porosity from the polarized image of the carbonate rock using the RGB values and grayscale values. Fig 6a shows the software architecture of the input, processing, and output of the RGB val- ues and gray values in the finite automata; and b shows the data processing of the RGB values and gray values in the finite automata. The first row in Fig 6c shows the original image of the carbonate rock slide, and the other images in c are the binary images and porosity values Fig 6.
