Mesh Optimization Guided by Just-Noticeable-Difference and Stereo Discretization

Although network speed has been increased over the years, bandwidth limitation continues to pose challenges to online applications requiring dynamic visualization. This is because the demand for instantaneous multimedia content far surpasses the network capability. It is therefore beneficial to suppress redundant data which does not contribute to visual quality in order to optimize resource utilization. When modeling photorealistic objects in 3D space, joint transmission of texture and mesh is required. In this paper, we propose an optimization strategy to reduce mesh data by transmitting only data perceptible to the human visual system. This strategy is motivated by the experimental finding on the just-noticeable-difference approach and the concept of stereo vision.
