Progressive rendering from RDTC optimized streams
Recently, we have introduced a framework for the compression and interactive streaming of image-based scene representations based on hybrid video coding techniques. In that scheme, the storage rate (R), distortion (D), transmission rate (T), and decoding complexity (C) are traded off against each other to minimize the user perceived delay in a remote navigation scenario. In this work, we extend that scheme by introducing a technique for progressive transmission and rendering from such RDTC compressed image-based scene representations. Real-time experiments show that a trade off between the user perceived delay and the rendering quality can be achieved and that the delay can be significantly reduced compared to independent or rate-distortion optimized compression.
