Converting Annotations from Pascal VOC XML to Coco JSON

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.

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/

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.

Yes. It's a custom license with an Acceptable Use Policy preventing military use and export restrictions. The custom license permits commercial use.

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.

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.

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.

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

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."

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...

I can't recall the true first time I used OpenCV because it's simply so embedded in all image processing work. I've backed the project, and my company has contributed as well.

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our hosted tools are used for image/video collection and annotation; dataset exploration with foundation models; model training; deployment to anywhere. Here's a simple webapp I made recently: https://josephofiowa.com/rps-embedded-vision23/

Over 250k engineers (including engineers from 1/2 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models[2]. We are pushing forward the CV ecosystem with open source projects like Autodistill[3] and Supervision[4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog[5] and YouTube channel[6].

We have several openings available, but are primarily looking for strong technical generalists. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function." At Roboflow, engineers aren't just responsible for building things but also for helping figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring founders.)

We're currently hiring full-stack engineers for our ML and web platform teams, a web developer to bridge our product and marketing teams, several technical roles on the sales & field engineering teams, and our first applied machine learning researcher to help push forward the state of the art in computer vision.
