Click on this map for a full-size annotated version. This is “Barclay, Clark & Co.’s 1893 Bird’s Eye View Chromolithograph” – a detailed, photo-like, colour drawing of Toronto at the end of the 19th century. Some artistic license emphasizes important…
Using AI for Literature Review
For 2 questions on the Psychology Stack Exchange, I compared a standard “manual” literature review process using Google Scholar to 4 AI tools for generating references. Note: I did not use AI to generate the answers. Rather, the AI tools…
Upscale video super-resolution using RSTT
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…
Using FFmpeg to replace video frames
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: Omit the -vf…
FFmpeg lossless filtering
Preserving Data Running a simple FFmpeg filter command: … 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…
The Age of COVID (update)
Canada’s COVID-19 vaccination program started in December, 2020, picking up in earnest by March, 2021. The program focused on the oldest population first, with over 90% of people over 70 years old at least partially vaccinated by the end of…
The Zombies
A short story on the philosophy of mind In one of the most extraordinary events in the history of humanity, contact was made with a sentient extraterrestrial intelligence residing some light years away from Earth. Though an in-person meeting would…
