Abstract

Previously, we have proposed a new methodology, which makes it possible to extract the physical properties from the visualized magnetic domains in ferromagnetic materials. This new approach to the sequential magnetic images is based on the modal analysis solution vector of initial value problems.<BR>In this paper, we apply this approach to the thermal infrared dynamic image in order to extract the physical parameters as well as regularity that dominate the dynamics of thermal distribution. As a result, it was difficult to extract the physical parameters as well as regularity dominating the dynamics of thermal distribution, because of complex heating and cooling conditions. However, it has been found that only few images are required to recover the precise infrared images by means of the equivalent characteristic values. Furthermore, applying the modal wavelets analysis to the infrared images well visualizes the heating situations.
