The two volume set LNCS 4291 and LNCS 4292 constitutes the refereed proceedings of the Second International Symposium on Visual Computing, ISVC 2006, held in Lake Tahoe, NV, USA in November 2006. The 65 revised full papers and 56 poster papers presented together with 57 papers of ten special tracks were carefully reviewed and selected from more than 280 submissions. The papers cover the four main areas of visual computing: vision, graphics, visualization, and virtual reality. The following topical sections are addressed: segmentation, tracking, and recognition, virtual reality, rendering, visualization, biomedical image analysis, visual computing and biological vision, understanding and imitating nature: analysis, interpretation, rendering and inspiration of biological forms, multimodal data understanding and visualization for industrial applications, intelligent environments: algorithms and applications, calibration, stereo, and reconstruction, computer graphics, discrete and computational geometry and their applications in visual computing, illumination, color, and texture, energy minimization approaches in image processing and computer vision, soft computing in image processing and computer vision, 4D medical data modeling, visualization and measurement, pattern analysis and recognition applications in biometrics, computer vision and applications.
