Learning with Verification: Improving Object Recognition with the Community’s Input
Thanks to our community that verified over half a million machine-generated object detections, we’ve developed an efficient approach to object recognition that helps improve map data quality. We used the verifications to include partially annotated images in our training data, leading to much higher detection accuracy compared to using only fully annotated images. This is a scalable way to get diverse training data for developing models that perform well on real-world object recognition tasks globally.

New Optical Flow Records using Mapillary’s Five Elements of Flow
In our latest work we reveal five key techniques for improving optical flow prediction — the task of estimating apparent 2D motion of every pixel in two consecutive images from a video. Our findings are the result of carefully analyzing shortcomings in existing works and thus help to improve a wide range of them. We quantitatively and qualitatively surpass the performance of directly comparable works and set new records on challenging optical flow benchmarks.
Achieving New State-of-the-Art in Monocular 3D Object Detection Using Virtual Cameras
We are introducing a new way of doing 3D object detection from single 2D images. The architecture is called MoVi-3D and is a new, single-stage architecture for 3D object detection. Starting from a single 2D image, it uses geometrical information to create a set of virtual views of the scene where the detection is performed using a lightweight infrastructure.
Unveiling our Latest Research: Multi-Object Tracking and Segmentation from Automatic Annotations
Access to high-quality training data is one of the most important requirements to push the boundaries with machine learning in computer vision. Today we’re unveiling our latest piece of research, where we roll out an entirely new way to generate training data for multi-object tracking and segmentation. The approach turns raw street-level videos into training data with unprecedented quality—even compared to results based on human-annotated data. By allowing machines to generate training data, the cost for training computer vision models can go down substantially. We validate our approach for multi-object tracking and segmentation and obtain new state-of-the-art results. Here is how.
