Exploring the Up-sampling Filter for Video applications (EVC-TEC) standard
A method typically used in video coding is to down-sample to half the input video frame before encoding. This reduces the computational cost but requires an up-sampling filter to recover the original video resolution in the decoded video to reduce as much as possible the loss in visual quality. Currently used filters are bicubic and Lanczos, Figure 1 – Up-sampling Filters for Video application (EVC-UFV) In the last few years, Artificial Intelligence (AI), Machine Learning (ML), and especially Deep Learning…
