A NOVEL APPROACH TO FACE RECOGNITION BASED ON THERMAL IMAGING

MG Sanjith Kumar, D Saravanan

Abstract: A novel approach to face recognition system based on thermal image is presented. The thermal images are captured using Thermal Mid Wave Infrared (MWIR) camera system at various temperature to take into consideration of subtle variations that may occur over time. The vasculature information from the image is extracted and used for matching process. Four images are used for registration process. The image registration is done with the Rigid Body Image Registration tool. Before registering Gabor filter is applied to the images and then filtered images are fused and registered. Face segmentation is done by localized region based active counters. The anisotropic diffusion filter is applied to an image and fused with the segmented image. The signature is then generated from the segmented image. Then templates are generated and stored for matching purpose. To perform authenticate the signatures are generated first and matched with the templates stored in the system
