Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.
[0031] The system architecture is designed as a tightly coupled structure that unites the server side and the client side (see appendix figure 1 ). At the source end, the original video signal (generally high-definition digital video (HD) source) is sampled non-uniformly and sparsely to form metadata, and the original resolution video is down-sampled and encoded into low-resolution and low-bit-rate video data; The data is transmitted on the network with the downsampled low-resolution video data; the high-resolution video is reconstructed by super-resolution interpolation technology at the client decoding end to provide good visual quality.
[0032] The whole process of non-uniform sparse sampling video super-resolution method (see figure 2 ) includes...
