OpenCV 5 Is Here: The Biggest Leap in Years for Computer Vision

“There is a CLI photogrammetry OSS project with rather litigious faculty members behind the code. However, at least that group was upfront about what was expected of the library users, and didn't do something dodgy like quietly merge it into another community library like OpenCV.…”

OpenCV 5 Is Here: The Biggest Leap in Years for Computer Vision

“Image augmentations library Albumentations is heavily based on OpenCV, which allows it to beat torchvision, Kornia, PIL, and other similar libraries. But there is still a huge room for improvement in terms of performance, as for some low level operations StringZilla or Numkong…”

Show HN: Canvas engines performance comparison – PixiJS, Two.js, and Paper.js

“My understanding is canvas also applies AA the rectangle lines still look AA just at a higher DPI. It looks to me like the rectangles done in WebGL are drawn at the scaled resolution (1920 x 1080) vs the unscaled resolution (3840 x 2160), whereas the canvas is DPI aware and…”

Show HN: Canvas engines performance comparison – PixiJS, Two.js, and Paper.js

“FWIW the code in the post doesn't use sprites. I think it is done intentionally because not all of the engines support sprites. As someone mentioned in this thread if PixiJS would use sprites, it could be 10x faster.”

Can't compile under Apple Silicon M1 arm64

“Did you see the [documentation relating to installation]( * yes Have you ensured the architecture and platform of Node.js used for `npm install` is the same as the architecture and platform of Node.js used at runtime? * yes Are you using the latest version? Is the version…”

Support for Windows

“I'd like to be able to use sharp on the Windows platform. Because `libvips` is available for Windows, I assume that lack of support is mostly in figuring out the build script. Has this been investigated already? If so, what approaches have already been tried and roadblocks…”

Benchmark: snapDOM vs html2canvas

“Yes, the default capture output is a svg dataurl. But there many other export options. This lib was made as an internal tool for another project called Zumly that is zoomable engine and the svg format was the faster output I found. But then I realized that could be an…”

Benchmark: snapDOM vs html2canvas

“For the 1st example, snapdom is not only faster, but actually correct, while html2canvas has some artifacts (on Linux/Firefox)”

Show HN: Nexus.js - Fabric.js for 3D

“Ha, that brings me back trying to make Fabric.js somehow usable for a 3D viewport at a startup I was working at a while ago. (We used esm.js instead of WASM for the 3d engine, to give you an idea) It was a lot of wrangling and unexpected behavior, and we ultimately ended up…”

Rembg is a tool to remove images background

“Rembg has been around for a while, but it’s still a really useful tool. It supports a wide range of adapters for different background removal models, including BiRefNet, which is definitely one of the best pre-trained image segmentation models.”

[BUG] ...RuntimeError: D:\a\_work\1\s\onnxruntime\core\session\provider_bridge_ort.cc:1029 onnxruntime::ProviderLibrary:

Support for high resolution file

“We can crop the image,use lama and paste back to the original image.”

Flask Server Stops listening,terminates itself

“It is not a bug but after some amount of time,I wasn't able to verify how much time required for that to happen but this windows shuts down itself on the background.So even the gui is in the foreground working,it is not able to process the image.I have seen this happen even in…”

Rough.js: Create graphics with a hand-drawn, sketchy, appearance

“I used it to implement the "Sketchify" generator in Boxy SVG ( ). It is especially nice that Rough.js has very few dependencies and can run inside a web worker.”

Remote code execution vulnerability in ImageMagick

“Thanks for linking to libpipeline; I didn't know about it. The API looks good. However, since it is licensed under the GNU GPL (the initial version was based on code in GNU troff) non-copyleft libraries like ImageMagick are unlikely to adopt it. If you are looking for a small,…”

Remote code execution vulnerability in ImageMagick

“> That being said, I wouldn't be surprised if porting those things over from compiled languages to be a part of the library would prove to be substantially slower. I must have missed something, I thought ImageMagick was a collection of C libraries and C programs, which in turn…”

Chrome aw-snap [works on version 4.3.7]

“I am building a web service where a user can upload and configure a 'card' which inherits a live preview of the vue instance as you modify the configurator component, the uploading works great throughout however I have narrowed it down to a total of 5 images allowed, where…”

Uploading File manually

“Is it possible to upload the file manually by letting the user click on a normal submit button alongside with a form either using ajax or direct post”

TypeScript import won't work

“None of the three methods detailed in the readme worked for me when importing gimp on my TypeScript project when upgrading to [email protected] I couldn't even access the right type so at least I can force a cast to require('gimp'). The error I'm seeing in the suggested methods is that…”

Collaborators wanted!

“Folks, When I created Jimp in 2014, I didn't expect it to become such an important part of so many projects. Over the last few months, there have been so many great feature requests, issues raised and pull requests. That's wonderful. It shows that there is a real community…”

Pillow-SIMD – Fast, production-ready image resize for x86

“> Do you have any links for further reading about downsampling banding and dithering? Sadly, no, I wish I did. I just made some expensive mistakes printing giclee images from downsampled digital files, and whipped up my own dither for converting 16bit to 8bit. It wasn't until it…”

Pillow-SIMD – Fast, production-ready image resize for x86

“I'd be very interested in an optional Pillow-SIMD downsampling resize that produces 16 bit output internally and then uses a dither to convert from 16 bit to 8 bit. Photoshop does this by default and it produces superior downsampling. Without keeping the color resolution higher,…”

TypeError: Cropper is not a constructor

“Hey, First thx for the amazing library. I tried to update my Ionic2/Angular2 project from Cropperjs 0.7.2 (who works like a charm) to the last version of Croppersjs 0.8.1. After this updated I'm now facing at runtime the following error: ``` browser_adapter.js:84 EXCEPTION:…”

Consider option to remove blank space around signature

“I need to use the sig image later in my app and the blank space around the sig can be a bit of a pain. I added an option to remove this blank space so that the image returned when I get the data is the cropped signature. I'm not sure if this would be useful to others, and I am…”

Capturing biometric data with the sign

“Hello. Is it possible to get biometric data associated to the sign? I say, writing speed, number of lines, etc. I need to be sure that the user doesn't reject the authenticity of his own sign for legal purposes. This component is the only one I've seen that writes a smooth sign,…”

Imgproxy: A fast and secure standalone server for resizing and converting images

“Imgproxy is such a reliable piece of technology, set and forget type of thing really. Put it in the cloud somewhere, add some CDN in front of it for caching and you're done. Also a huge money saver when compared to Imgix/Cloudinary/etc offerings.”

Imgproxy: A fast and secure standalone server for resizing and converting images

“Static linking is now allowed as libvips is licensed under LGPL and imgproxy is licensed under MIT. What’s wrong with dynamic linking BTW?”

Pixelorama snap

“Hi! I saw that someone ( probably @Schweini07 ) already registered the "pixelorama" name in the snap store. This is great! I have already a working snap version of pixelorama 0.6 and I would like to share it with you so you don't have to [waste your time reinventing the wheel](…”

High CPU Usage

“Hello, i notified that the Pixelorama eats 2 cpu cores while in idle completely. I have a laptop with Intel Core i7 7600U (2 Cores - 4 Threads) running Fedora 31. Pixelorama is permanently at 50-60% in htop, for comparison the godot editor at only 5%.”
