In a deformation progress of a polyvinyl chloride sheet, the coupled deforming heat is recorded by a thermal infrared imager. In order to have a real-time study for the variation regularity of the deforming temperature field distribution, all infrared images are imported into MATLAB software as digital data through a dynamic link routine compiled based on MATLAB and Windows. By utilizing a gradient-based transition region extraction algorithm and an interpolation algorithm, the high-resolution recognized and reconstructed infrared images are obtained from original blurring images recorded in t...
