pixelmatch VS immich

I'm the dev for a javascript-based reddit bot that implements image comparisons using both pixel matching and/or perceptual hashes (that could be stored in a DB). I'd be happy to go over high-level or implementation details if its something your team would be interested in. Either on github or elsewhere.

There are quite a few image comparison libraries in pure Javascript for both node and browser.

You could absolutely get this working with GitHub Actions with a bit of creativity.

I've been playing around with my own image-diff tool for this kind of thing, but it's not yet in a decent state: https://github.com/simonw/image-diff - there are other, better options out there such as https://github.com/mapbox/pixelmatch

Needle is an older system that did this using Selenium - updating that to work with Playwright (or Playwight via shot-scraper) would be an interesting project: https://github.com/python-needle/needle

Internally, Playwright Test uses the pixelmatch library to compare screenshots for visual differences. It is possible to pass several options to this library, to fine-tune the comparison of images. The most important option is the threshold option, which indicates the threshold amount of differences allowed between two images.

Other use-cases include combining screenshots with the Autocode scheduler, a file hosting platform like Box, and a package like pixelmatch to create daily screenshot diffs for regression testing.

It really is hard to leave Gmail when all of your data has been conveniently stored therein. This is one of Google's retention strategies and it is indeed brilliant.

That said, there's a vast number of self-hosted alternatives like Stalwart Mail (email) [1], Immich (images) [2], NextCloud (Google Docs) [3], etc.

Last year we added CLIP-based image search to https://immich.app/ and even though I have a pretty good understanding of how it works, it still blows my mind damn near every day. It's the closest thing to magic I've ever seen.

I’m a big fan of https://immich.app/ and I use it every day for thousands of assets

Real-world applications often require complex queries that go beyond simple Approximate Nearest Neighbor (ANN) search. To explore a practical example of such applications, let's take a closer look at immich, a self-hosted photo and video backup solution that highlights the importance of advanced vector and traditional relational queries.

I discovered these 3 amazing projects recently:

Cryptpad, essentially google docs/sheets/forms e2e encrypted. It does include collaboration. https://github.com/cryptpad/cryptpad

Immich, google photos self hostable, with share options https://github.com/immich-app/immich

Nginxproxymanager manages certificates and proxies to self hosted stuff through nginx https://github.com/NginxProxyManager/nginx-proxy-manager

Great self hosting stuff!

I realize it's very hard, but can we maybe reconsider opening the encryption-at-rest feature request? https://github.com/immich-app/immich/issues/450

Maybe we can give temporary access to processing steps in the pipeline, then have Immich forget the keys after it does the processing?
