In recent years, research of bleaching of coral based on change of underwater environment is important in order to know change of global environment. Currently, investigation of underwater is conducted by the diver. Therefore, several problems such as load for the diver and restriction of search area are occurred. To solve these problems, we are developing the underwater robot for investigating of coral reef for the wide and the long time. In here, to know the current situation of coral we consider the automatic extraction method of the coral based on texture analysis from image obtained by monitoring.
