strip-p-ed out

A 3 months #research around #patterns to bypass #cctv #facerecognition.
Tested with #opencv.
Project done in the #fabricademy, a programme over textile and technology, at the @greenfabric node.

I knitted 2 kimonos on a #kniterate, a semi-industrial #machineknitting with deadstock yarns. The 3rd one is a deadstock fabric whose pattern was already a working #camouflage for opencv.

The project is fully documented here:
class.textile-academy.org/2024

Concerning cctv surveillance, France has recently gone crazy over it... it seems like they want to recognise logos from organisations in protests and faces associated with them... does someone know an opencv algorithm to detect specific images? Or does it necessarily go through machine learning?

Hey #OpenCV #ComputerVision #Python

I would like to point a camera at an area of the house and have it announce when a dog has entered the camera frame.

I am quite handy with Python and can muddle my way through C-like stuff if I have good documentation or example code.

Is this easy or hard? Hard is not a dealbreaker, just trying to tune my expectations a bit.

edit: strictly speaking, it only needs to spot two dogs, that I have many photos of, but a generic dog detector would also be fine.

Continued thread

For those interested the map is made with #QGIS and #OpenCV for #Python

The animation is driven by an expression that uses time and magnitude of each earthquake to change the size of each point. Something like:

coalesce(scale_polynomial("magnitude" * day(@map_start_time - "time"), 0, 15, 2, 10, 0.57), 0)

Can a poor open source project get an assist from some kind Wikipedian? The @opencv logo is out of date by several years and it annoys me to no end. People keep using the old logo. I do not have the edit powers to fix it. The old logo being used on Wikipedia pages is en.wikipedia.org/wiki/File:Ope and the correct, current, logo that we use is opencv.org/media-kit/ #Wikipedia #OpenCV

For me, the most waited and exciting presentation at #PyConUS24 was Jim's (@hx2A) talk: #CreativeCoding with #py5 (@py5coding), the #Python version of #Processing

If you missed it, you can watch it now! youtube.com/watch?v=pNVn3FPi5P

I'm so glad I was able to be there! We had a nice "creative coding open space" the next day. I wish @ericof and @TomLarrow could have been there too. #numpy #shapely #trimesh #matplotlib #opencv

Do I have anyone in my wider network with skills in programming CUDA, SYCL, and OpenCL?

We want to determine feasibility of migrating CUDA-only code to SYCL (via SYCLomatic?): OpenCV feature detection/extraction modules (SIFT, HAGOG, ORB, AKAZE).

The intent is to upstream all feasible work.

This, hopefully, should stand to benefit everyone instead of being limited to NVIDIA.

Currently in info gathering/people connecting phase, not yet funded & ready to go.
