IRTROCK: A MATLAB toolbox for contactless recognition of surface and shallow weakness of a rock cliff by infrared thermography

► A series of thermal images allows the analysis of temperature pattern evolution. ► Weakened rock and sound rock have different thermal transfer efficiency. ► Surface weakness of a rock mass can be recognized with infrared thermography. ► A MATLAB toolbox able to perform this recognition has been developed. ► Cases study: Valstagna-Contrada Pieretti and Caprile (North-Eastern Italian Alps).
