Infrared thermography, its modeling as well as applications are described in this extensive book. To diagnose casualty and provide therapeutic action, Infrared Thermography (IRT) is used as a Nondestructive Examination (NDE) tool. The areas of application of this tool constitute a wide range varying from materials science, life sciences and applied engineering. The book encompasses various important topics, which are connected to utilization of infrared thermography to analyze issues in materials science, agriculture, veterinary and sports fields; and also in engineering applications. Both arithmetical designs and research approaches of IRT have been described in the book. The book has been compiled with an aim to provide the readers with requisite knowledge about IRT and garner more interest for research in this domain.
