Hanging out with @KostasPenn! I’ve been very fortunate to have such AWESOME mentors and role models. Future home of the @Penn #datascience building.

My online setup: The only difference is I swapped out the Sony headphones for lightweight Apple AirPod Pros. In terms of software, I use Open Broadcaster Software (OBS) to put together my various streams (Keynote slides, video, audio) & then send to Zoom. https://t.co/aAewZeJw2t

ALERT: This is NOT the IEEE/CVF International Conference on Computer Vision (ICCV). This has caused at least one case of confusion to a new member in our #computervision community.

One thing I missed during the pandemic was grocery shopping alone with a podcast. Check out the @twimlai podcast “The Benefit of Bottlenecks in Evolving Artificial Intelligence” with @hardmaru! https://t.co/Ewi0GdEnHC

Given we are at the #CVPR2022 AC onboarding stage, check out @cgmsnoek and my talk about ACing at the #ICCV2021 tutorial on "Reviewing the Review Process". Had a BLAST preparing this talk. At some point will watch it but uncomfortable watching myself. https://t.co/WRIPx0X0uZ

Fresh take on undergrad linear algebra: Linear algebra AND Coding!

Shared by Kosta Derpanis at 9/24/2021

Cover it in my computer vision course. Can simply be explained with the perspective perspective equations. Both the focal length and the camera distance to the subject is changing in such away that only points at a specific distance project to the same points in the image.

For a more geometric take on #computervision check out @KostasPenn and Jianbo Shi's amazing Coursera course (Robotics: Perception). Treasure trove of content not found in typical vision courses. https://t.co/8xCyWGe0O7

And another lecture on geometric #computervision waiting to be delivered eventually. Also who needs stock images, when you have kids 😉

After teaching intro to #ComputerVision for a decade, my lecture slides remain in perpetual refinement. Finally, got around to putting together a short unit on bilinear interpolation for my course.

I’m a big fan of ego-stabilized feature maps using spatial/geometry-aware RNNs that both @karpathy presented at Tesla AI day and @AdamWHarley and company have been pursuing over the past few years.
