Time-Based Image Averaging

Imagine watching a time-lapse video covering more than a century that shows the evolution of a landscape, a magazine cover, trends in fashion, or automobile design.  Or picture the same thing being done with the face of a politician or celebrity from youth to old age, or with artistic trends in painting spanning a millennium…

Improvements in Face Averaging

The historical face-averaging experiments I’ve been blogging about here for the past couple years have depended on efficient, decent-quality methods of averaging faces in the first place.  I’ve recently figured out some ways to improve my results and streamline the process of getting them, and in this post I’d like to describe my latest revised…

My Fiftieth Griffonage-Dot-Com Blog Post

This blog made its debut just under two and a half years ago, and since then I’ve published a new post every two and a half weeks on average, bringing the total—if we include this one—to fifty.  That’s a nice milestone to have reached, and it gives me a good excuse to reflect on what’s…
