Re:Meta Segment Anything Model 3 on Wednesday November 19, 2025 @05:23PM (#45986139)
As someone that works on a platform users have used for labeling 1B images, I'm bullish SAM 3 can automate at least 90% of the work. Data prep is flipped to models being human-assisted instead of humans being model-assisted (see "autolabel" https://blog.roboflow.com/sam3/). I'm optimistic majority of users can now start deploying a model to then curate data instead of the inverse.
Re:Meta Segment Anything Model 3 on Wednesday November 19, 2025 @04:17PM (#45985334)
A brief history. SAM 1 - Visual prompt to create pixel-perfect masks in an image. No video. No class names. No open vocabulary. SAM 2 - Visual prompting for tracking on images and video. No open vocab. SAM 3 - Open vocab concept segmentation on images and video.

Roboflow has been long on zero / few shot concept segmentation. We've opened up a research preview exploring a SAM 3 native direction for creating your own model: https://rapid.roboflow.com/

Re:Meta Segment Anything Model 3 on Wednesday November 19, 2025 @04:09PM (#45985218)
The model supports batch inference, so all prompts are sent to the model, and we parse the results.

I tried it on transparent glass mugs, and it does pretty well. At least better than other available models: https://i.imgur.com/OBfx9JY.png

Curious if you find interesting results - https://playground.roboflow.com

Re:Meta Segment Anything Model 3 on Wednesday November 19, 2025 @03:59PM (#45985087)
Yes. But also note that redistribution of SAM 3 requires using the same SAM 3 license downstream. So libraries that attempt to, e.g., relicense the model as AGPL are non-compliant.
Re:Meta Segment Anything Model 3 on Wednesday November 19, 2025 @03:54PM (#45985024)
Yes. It's a custom license with an Acceptable Use Policy preventing military use and export restrictions. The custom license permits commercial use.

Re:Rivian's Also E-bike is like nothing you've ever seen on Thursday October 23, 2025 @12:52AM (#45678263)
The bike lane compliant vehicle category is exciting. Infinite Machine (infinitemachine.com) made me aware of this category with their Olto model, which is at a (surprisingly) superior price point.
Not nearly enough gradient for a vibe coded site :)

One of the most common uses for edge AI not listed in this course is computer vision. You similarly want real-time inference for processing video. Another open source project that makes it easy to use SOTA vision models on the edge is inference: https://github.com/roboflow/inference

both the endeavor and the site are super cool - congrats on 10 years. interaction on the graphics would be a nice touch to select into a specific run. went looking for the code on your GH! https://github.com/friggeri
In the 2019 fatal Tesla Autopilot crash, the Tesla failed to identify a white tractor trailer crossing the highway: https://www.washingtonpost.com/technology/interactive/2023/t...
I wonder how long until techniques like Depth Anything (https://depth-anything-v2.github.io/) provide parity with human depth perception. In Mark Rober's tests, I'm not sure even a human would have passed the fog scenario, however.
Re:AI Demos by Meta on Sunday February 09, 2025 @04:54PM (#42994461)
Meta deeply comprehends the impact of GPT-3 vs ChatGPT. The model is a starting point, and the UX of what you do with the model showcases intelligence. This is especially pronounced in visual models. Telling me SAM2 can "see anything" is neat. Clicking the soccer ball and watching the model track it seamlessly across the video even when occluded is incredible.
Re:Video Surveillance with YOLO+llava on Tuesday October 08, 2024 @01:12AM (#41774036)
A suggestion: I'd swap llava for Florence-2 for your open set text description. Florence-2 seems uniformly more descriptive in its outputs.
Re:Segment Anything Model and Friends on Sunday August 11, 2024 @06:32PM (#41219761)
SAM 2's key contribution is adding time-based segmentation to apply to videos. Even on images alone, the authors note [0] the image-based segmentation benchmark does exceed SAM 1 performance. There have been some weaknesses exposed in areas of SAM 2 vs SAM 1, like potentially medical images [1]. Efficient SAM trades SAM 1 accuracy for ~40x speedup. I suspect we will soon see Efficient SAM 2.

Re:Sam 2: Segment Anything in Images and Videos on Monday July 29, 2024 @08:15PM (#41104928)
One thing its enabled is automated annotations for segmentation, even on out-of-distribution examples. e.g. in the first 7 months of SAM, users on Roboflow used SAM-powered labeling to label over 13 million images, saving over ~21 years[0] of labeling time. That doesn't include labeling from self hosting autodistill[1] for automated annotation either.

[0] based on comparing avg labeling session time on individual polygon creation vs SAM-powered polygon examples [1] https://github.com/autodistill/autodistill

"Load Example" was very helpful to get a sense of what this does. Awesome build. +1 to the other comment wanting a breakdown of what the colors mean.

Also, combining this with real-time in-game camera play could be really powerful, too[0]. Like illuminating details during the game.

i work on roboflow. seeing all the creative ways people use computer vision is motivating for us. let me know (email in bio) if there's things you'd like to be better.
Re:Vision Transformers Are Overrated on Monday April 01, 2024 @09:38PM (#39901467)
Pulling out a key part of this post from a DeepMind 2023 paper[1]: “Although the success of ViTs in computer vision is extremely impressive, in our view there is no strong evidence to suggest that pre-trained ViTs outperform pre-trained ConvNets when evaluated fairly.”

Another common constraint in vision vs language is the long tails are very long in the visual world. There's a number of domains where you have very little examples to learn (defects are designed to happen infrequently; rare species for identification show up, well, rarely). And pulling from the blog: "But small models ... benefit greatly from the exact type experiment of outlined in this post: strong augmentation with limited data trained across many epochs."

Re:Suno AI on Saturday December 23, 2023 @10:26AM (#38744860)
suno has improved fast. I remember when they released Bark in April ‘23. it was good. but this new model is fun. props to the team.
Really neat. I tried your search for red shoes, and I found some, er, unexpected imagery on page 1.

One thing you could do is add semantic search so when a user searches "red shoes," the index returns images that look like red shoes even if the metadata doesn't say anything about color or item types. To do this, I'd use a model like CLIP. Here's an example of using CLIP and Supabase to do semantic image search: https://blog.roboflow.com/how-to-use-semantic-search-supabas...

In your inference project example, what examples do you place in Getting Started vs common usage examples? In general, where is the best place for usage examples - alongside the methods they use, or in an independent section?
