Increase video resolution with an opensource machine learning algorithm for upscaling video image frames using an automated command line script. Bringing machine learning algorithms a step closer to usability. Given a low-resolution video file, this script uses a machine-learning algorithm to increase (upscale) each frame’s resolution using information from neighbouring frames. The workhorse is . . . → Read More: Upscale video super-resolution using RSTT Machine learning algorithms for video processing typically work on frames (images) rather than video. In a typical use-case, FFmpeg can be used to extract images from video – in this example, a 50-frame sequence starting at 1:47: >ffmpeg -i input.vid -vf “select=’gte(t,107)*lt(selected_n,50)'” -vsync passthrough ‘107+%06d.png’ Omit the -vf option if extracting the entire video. . . . → Read More: Using FFmpeg to replace video frames Preserving Data Running a simple FFmpeg filter command: >ffmpeg -i input.vid -filter_complex “[v:0]copy” output.vid … one might expect the output video to be the same as the input video. Note that both input and output videos use the same container format (file name extension), and the command just uses the “copy” (do nothing) filter, . . . → Read More: FFmpeg lossless filtering Canada’s COVID-19 vaccination program started in December, 2020, picking up in earnest by March, 2021.

However, other models projected that travel bans could be highly effective. As . . . → Read More: Were early travel bans effective against the spread of Covid-19? |
