Abstract :
Summary form only given. Existing distortion measurements for the B-spline-based shape coding include ap proximation, quantization, or parameterization process, so they are approximate techniques. They may inaccurately predict the actual distortion value, which motivates us to construct a model that can accurately measure the actual distortion. It was reported that the actual distortion for reconstruction quality assessment is the minimal Euclidean distance between each associated contour point and the reconstruction contour.
