Abstract

In an infrared (IR) image sequence of human walking the human silhouette can be reliably extracted fromthe background regardless of lighting conditions and colors of the human surfaces and backgrounds in mostcases. Moreover some important regions containingskin such as face and hands can be accurately detectedin IR image sequences. In this paper we propose akinematic based approach for automatic human motionanalysis from IR image sequences. The proposed approach estimates 3D human walking parameters by performing a modifed least squares fit of the 3D kinematicmodel to the 2D silhouette extracted from a monocular IR image sequence where continuity and symmetryof human walking and detected hand regions are alsoconsidered in the optimization function. Experimentalresults show that the proposed approach achieves goodperformance in gait analysis with different view angleswith respect to the walking direction and is promisingfor further gait recognition.
